thanks for letting me know.

What you are asking for could actually be done with a custom action 
and a one liner in a contained AppleScript Actor:

tell application "Remote Buddy" to behaviourcore accessor 
"setActiveBehaviour" identifier "com.iospirit.input.mouse" 
useActivationEventCode "activated" with stickyValue

(should Apple Mail break aboive line: this is all in one line)

The next version will very likely include that functionality already, 
though.

Best regards, 
Felix
