Triggering a rule on demand

I'm currently using Keyboard Maestro to help in synchronising two machines. I use a keystroke to start my synchronising app, but I want Hazel to collect the "archived items" (ones which have been moved, but copied to safe folders) into one big folder. TO do this I would have a rule in Hazel ("CleanUp") which I would trigger to run at the end of the Macro.
Is this possible?
Thanks in advance
