Specify [gesture] in SendKeys - run gesture from another gesture

I would really like to be able to define one action, then use that action in several commands.

For example, I have four gestures that I use to make remote connections. Part of the gesture is to send a password. I'd like to be able to put that password in it's own "macro" and have it used by the four gestures. That way I would only need to edit it in one location instead of four.

Since we can already use [alt_down], etc. in the SendKeys command, why not [myGesture] or even [[myGesture]]???
