Notification of What Other Triggers Are Assigned to that Key

It would be really helpful if you could easily see if you've already assigned a trigger to a certain key (while still having the option of having multiple triggers on a specific key) so that way, on more complex puppets, you don't risk having two unrelated triggers happening at once. Something like how in InDesign, when you create your own shortcuts for Character/Paragraph Styles, there's a notification if you've already used that shortcut.

Thanks!
