I noticed someone on FT8 operating for a while with a /M suffix. So I guessed /P might be, in a way, possible, and tried it myself.
It is indeed possible, but I soon realised the limitations. Because (at present) WSJT-X cannot understand or handle /P, it doesn’t see it. So if calling CQ as M1EYP/P, if someone replies, they reply to M1EYP. The consequence of this is that the autosequenced QSO is not launched; the activator needs to keep his eye on the left hand window for incoming calls, and manually select and launch the QSO sequence.
So it is possible, but it’s not slick - or indeed much fun. I swiftly went back to using just “M1EYP” and trusted the SOTA chasers to know that it was really M1EYP/P on the summit. As for the non-SOTA chasers - well, who cares?
But this development will eradicate WSJT-X’s most obvious and irritating deficiency. That pleases me, because I enjoy activating via WSJT surprisingly greatly. I’ll tell you what though, despite suggestions to the contrary, CW is still MUCH faster and MUCH more effective! Then again, with the WSJT upgrades, the possibility opens up for the SOTA activator to explore the potential of DXpedition mode…
