Yes, that's exactly how it is @qwertycolemak. I created a macro group for each app (Pages, Mail, Safari etc.) and need only one and the same three finger swipe gesture for all of them.
Just like in this example, I have different macro actions (put in trash etc.) in my Finder macro group.
But I can also point to another app (here Cloud App) as sub macro and share a file very fast.
Thanks to BTT I don't need any triggers like shortcuts or type string triggers in Keyboard Maestro. Everything is controlled by a swipe gesture.
If it helps you, I can make a short video tutorial in English for you.
