at least part of that is going to be worked on soon 
unfortunately, I don’t see any way of detecting what difficulties a song has charted beyond opening it in reaper and comparing the charts. even a midi parser would see that EMHX have charts, but do we really want to start comparing note by note to provide the final result = “this is an x-only song”? I at least don’t see the use in that.
but seeing what instruments are charted and the chart difficulty tiers…i do…so I may be planning to do something about that.
