Is your feature request related to a problem? Please describe.
Recently in the past few months there was a change added to Player/Unit Info -> Health where you could specify Unit Name/NPC ID/etc, this was a useful addition that made it easy to track the health of certain nameplate units. It would be nice to apply this change to Threat Situation too if possible.

Describe alternatives you've considered
Far as I know, the only alternative atm are custom triggers if you want to track aggro on certain nameplate units.
