Is it possible to keep a piece selected until a Key command?

I don’t know if this is possible, but i’d like to be able to:

  • right click on a piece and pick a (as example) “Activate” menu item
  • the piece is now selected and no matter what i do or where i click, it will always stay selected
  • right click on a “End Activation” menu item and then it will loose “focus” and i can pick anoter piece.

If this is possible, then i’d like also to be able to pick another piece as “target” so i could use commands from the selected one that will affect the Target (like “kill” or “heal” or “buff”, and having traits and global keys commands that will changes target properties).

Are any of these points doable?
