Thankyou both for your help!
Here's what I'm dealing with. With the exception of the two macros I've darkened out, these all load UAD Console presets (an audio routing app). As you can see from the highlighted example, each of them opens a different preset file.
I've been using the KMLink parameter box with great success for simple text pasting, but converting that into choosing a file to open had me scratching my head.
The good news is the Switch idea works great! I set the clipboard to variable %TriggerValue% and then use the Switch/Case action to create the list. Perfect!!!!
Thankyou so much!
