Confused on Adding Track

[magaman]

I just added the integration as we are near an airport and I wanted to figure out what are the various helicopters circling at times, without having to jump into the FlightRadar app. I have the helicopter callsigns saved that I wanted to track and then alert on when they are in the area. I assumed it was as simple as adding a track and then that would show me when any of the added tracks added are in the area, but that doesn't seem to be the case.

I'm trying to wrap my head around how I would then filter the list of in the area to only list or count this set of callsigns.
