I would find it useful to have the International FIR boundary estimate on the PLOG (perhaps as a pseudo waypoint) as that’s often asked for by ATC.  I have learned from the other forum that I can press and hold and select “what’s here” to get it, and that its also on the ATC FPL (which I knew but it doesn’t update in flight obviously, not is easily accessible).  Obviously You can create a waypoint at the boundary but in doing so it often slightly changes the track in/out and if using many different routes means many different user waypoints.

Any thoughts?  Thank you.
