app.config file

Question

In a C# 2010 application, I want to place files in dynamic folder structures that I create in the application. I want to create these dynamic locations so we can place data in the dynamic paths based upon customer name. I also wantto place these dynamic paths in the app.config file.

Thus can you tell me if there is a way to point the app.config file to these dynamic paths? If so can you tell me and/or point me to a reference I can use that will help me accomplish this goal?
