Need to Build a APM Portal for Client and have a dynamic resource assinged using Rewrite of URI

hope someone can help me understand how to build a APM Portal which uses dynamic resource assignment using a resource rewrite.

 

The server that they need access to is blocked by their local proxy and they will not allow it so i need to present them with an URI that is allowed like https://google.com/forms

 

but then have the APM do a resource rewrite to the URI below: https://server.ourdomain.com/programview.jsp

 

thanks in advance any insight or help anyone can give.
