<R65> seems clear to me, that you can communicate only 4 messages during any single match. <R69> says you can't change which 4 messages it reacts to during a match.

So, in my opinion*, as long as you set which 4 you're using before the match, don't change during the match, have the card mentioned in <G49> accurate, it should be OK.

*Which isn't worth anything at the competition.
