There seems to be a lack of trigger results that impact the Watchlist. Specifically:
There's no trigger result for removing someone from the Internal Watchlist. There's a trigger result for adding someone to the Internal Watchlist - so why not for removing someone from the Internal Watchlist?
There's no trigger result for adding/removing specific email address to/from the External Watchlist. Sometimes I have a specific external email address I either want added or removed from the External Watchlist based on other criteria - but there's no functionality for that.
It just seems silly that the only function you can really do is add someone to the Internal Watchlist and nothing else.
