I just quite using drum maps in Step Sequencer, and I have a laminated Word doc page with a table showing the kit pieces for each note number/name, but I long ago just memorized which notes are assigned to which drum kit pieces, so it isn't an issue for me.
I had posted about this issue going back as far as either 8.5.3 or X1 (can't remember which), so this has been out there for quite a long while and I don't think they are going to change things anytime soon.
