Well those are actually GPIO (or GPI / GPO) pins, so we might want to add some alternate name also on them depicting this.

For example, we could name H6  P17/GPSMODE5/SCK1/UDIO17 or something similar (UDIO: User-Defined IO)

But since we have P17 there might not make much of a sense. However some P\d+ pins are not user configurable.
