Web Dynpro URL for DEV, QAS, and PRD

Hi,

I have a Web Dynpro IView in my DEV System with a Static Address (See below Link for example image). I'd like the address to be dynamic depending on the system it is in. This IView will exist in our DEV, QAS, and PRD System so I need to somehow have the server and port be dynamic depending on the system. The system dropdown in the IView Configuration doesn't present any selections so I'm not sure how to get through this. I did search SDN and didn't find anything.

Can anyone step me through this?
