Problems with web.config and app.config

Question

I have a DLL that references a web service.

The block that he placed in app.config (I changed the names, but you get the idea):

<applicationSettings>
    <DLLName.My.MySettings>
        <setting name="DLLName_WebReferenceName_ASMXName"
            serializeAs="String">
            <value>http://URL/Filename.asmx</value>
        </setting>
    </DLLName.My.MySettings>
</applicationSettings>

My site is linking to this dll.

The question is, what can I add to web.config to override the above parameter (alternatively, just put app.config in the BIN directory)?

I need to redefine the web service url on the production server because it cannot reach the url specified in app.config (this is another problem that we will not enter).

            <section name="Playground.ConfigurationOverride.DataAccess.Properties.Settings" 
                    type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" 
                    requirePermission="false" />
        </sectionGroup>
    </configSections>
    <applicationSettings>

            <setting name="MySetting" serializeAs="String">
                <value>Setting in DataAccess</value>
            </setting>
        </Playground.ConfigurationOverride.DataAccess.Properties.Settings>
