Tool modifier..can you add more actions?

So I go into preferences and navigate to tool modiers.
Under category ‘select tool.’
I can pick a key or keys then assign to an ‘action’
Great feature which I use a lot…
With ‘select tool’ the ‘alt’ key to snip a part is one I use a lot…
can I add extra ‘actions’ to the list…?
For example ‘alt shift’ to glue parts together
So I’d have a combination with select tool of:
Alt = snip
Alt+shift = glue
Thx for any help

Only the Steinberg developers can do this, I’m afraid.

Yeah kinda what I expected…thx
