Binds with .!xxxxx in them.

[SO•Marty]

This is nitpicking of the highest order, but anyway.
I'd like to make a bind that says:

"CAUTION @ !location", thats easily deployable when needed.
I know I can do 2 messages: bind: "Caution @" and a bind "!location" but since I drive with Ks I am running out of easily reachable binds, and I prefer 1 bind instead of 2 to prevent spamming the chat. Would this be possible, or are "!xxxxxx" automatically disabled when there is other text in the textbox?
