Mapping of Sources?

First off, thanks for picking this up and moving forward with it. So I have a Denon AVR-X2000 and am running UI7. When I look at the receiver in the device details I see my sources as named. What I’m trying to do is switch sources on an event but when I try to use the advance scene editor the actions for the receiver shows different sources.

Is there an easy way to figure out the mapping vs. trying every source or input?

Under the Volume/Inputs tab you can cross reference the actual input names and assigned input names.

I see it, thanks!!!
