Allow for setting an external rule to be fired in the event triggers via API/iLogic. As I understand it, there is currently no direct way to accomplish this. I am aware of the "create an internal rule to run the external rule..." work around, but that's ugly.
This is needed for updating old files to use new and shiny automation without a lot of excess clicking (and relying on my co-workers to remember to do it).
There is also an idea floating around here somewhere for adding "Global Event Triggers". If this were implemented, it would solve my problem.
