[CQ-Contest] An identifier for Multiple QSO Parties?

[Lloyd Cabral]

This past weekend included a multitude of State QSO Parties.      This year I was only interested in operating the 7QP.
Despite calling CQ 7QP, I was often called by stations in the other QSO Parties.     Perhaps it's time for a CQ to indicate
you're into all the QSO Parties.     We currently call CQ 7QP,  NE, IN or DE to play in one of them.     How about something
like CQ MP to confirm you're operating in Multiple QSO Parties?      If you're playing in all of them, call CQ MP.      Without
a unique identifier, many stations assume you're participating in all of them.      Seems like it would be an easy fix.
