Thank you! That makes things better.

Technically, it seems to work (you can only select 1), but the menu system is a little flakey when you try jumping back and forth between what device to select. Somehow when 2 get selected, I need to get kbuild to go back and do a full refresh or something.


I'm going to play with it some more before I start shouting victory.
