What is sidechaining what feature request.

I often have lots of tracks and lots of side chains set up.
Sometimes If I look at the effects bin I see a compressor that I put there to be side chained by some other track.
Time goes by and, I will have no idea what track is triggering that compressor. It would be nice if there was some sort of way to see what track/send is triggering it.
The send or output will show what it is sending to, but, the receiving end, in this case the compressor,  does not.
 
Thanks
