You can place your entire current report (excluding headers and footers) in the list object. I assume that you are returning selected values from a parameter (e.g. manager name) as part of your DataSet. Assuming this is so.
Create a new list
Paste the contents of your report into the rectangle of this list.
Right-click the row list header and select a row group -> Group Properties
Set group for group work
=Fields!ManagerName.Value
This approach will take a simple table like this

And break it down into a list like this

Then you can simply set the tablix properties of the list Add a Page Break Afterto check
Hope this helps. If you have further questions about this, please let me know.
