Soft key macro for playback mask?

Id like to know if there is a way to mask parameters a chosen master by using soft keys.
I wanna wright a macro that enables and disables paramter masks on my cue list without having to use screen presses.
Macro: Choose master 9/1 -> Softkey lower right 10 -> ???
i tried many things but cant find a way to make it work. Maybe there is another way?
If this isnt possible yet, i would love to see this option in the future.
