Vertical Scrolling for HubSection Content

Question

I am working on a Windows Phone 8.1 (Windows Runtime) application and I created a page with the following location:

<Grid Grid.Row="1" Margin="0, 10, 0, 5" >
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <maps:MapControl x:Name="LocationMap" Grid.Row="0" Height="220" 
                                 MapServiceToken="..."/>
        <Hub Grid.Row="1" Margin="0, 25, 0, 0">
            <HubSection Header="ABOUT" x:Name="AboutHubSection">
                <DataTemplate>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <Grid x:Name="ShortDescriptionPanel" Grid.Row="0">
                            <Grid.RowDefinitions>
                                 <RowDefinition Height="Auto"/>
                                 <RowDefinition Height="Auto"/>
                            </Grid.RowDefinitions>
                            <TextBlock Grid.Row="0" local:TextBlockExtension.FormattedText="{Binding ShortDescription}" FontSize="16" TextWrapping="Wrap"/>
                            <TextBlock Grid.Row="1" Text="Show more" Visibility="{Binding IsDescriptionTooLong, Converter={StaticResource BoolToVisibilityConverter}}" FontSize="16" Foreground="{StaticResource PhoneAccentBrush}" Tapped="OnShowMoreTapped"/>
                        </Grid>
                        <Grid x:Name="FullDescriptionPanel" Grid.Row="1"
                                            Visibility="Collapsed">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto"/>
                                <RowDefinition Height="Auto"/>
                            </Grid.RowDefinitions>
                            <TextBlock Grid.Row="0" Text="{Binding FullDescription}" FontSize="16"  TextWrapping="Wrap"/>
                            <TextBlock Grid.Row="1" Text="Show less" Visibility="Visible" FontSize="16" Foreground="{StaticResource PhoneAccentBrush}" Tapped="OnShowLessTapped"/>
                        </Grid>
                    </Grid>
                </DataTemplate>
            </HubSection>
            <HubSection Header="RSVP" x:Name="RsvpHubSection" Margin="0, 0, 0, 50">
                <DataTemplate>
                    <ScrollViewer>
                        <TextBlock FontSize="16" TextWrapping="Wrap"
                                Text="{Binding RSVP}"/>
                    </ScrollViewer>
                </DataTemplate>
            </HubSection>
            <HubSection Header="Statistics" x:Name="StatisticsHubSection" Margin="0, 0, 0, 50">
                <DataTemplate>
                    <ScrollViewer>
                        <TextBlock FontSize="16" TextWrapping="Wrap"
                                Text="{Binding Stats}"/>
                    </ScrollViewer>
                 </DataTemplate>
            </HubSection>
        </Hub>
    </Grid>
</Grid>

Thus, the content of the page consists of a map control that takes 220 height units, and the rest is a hub with three sections. HubSections should have their content for VerticalScrolling, if so.
