There is no accepted alternative for a DS4 pad in the MKX community.
This should be reconsidered and instead the desync rule should be applied.
Players who come onto a setup are responsible for removing the previous controllers from a setup.
If they do not know how, the judges should show them.
It has been proven that this prevents pauses from games, and if a pause actually happens the judge
must enforce that the players are forced to either continue without replaying or restart the round/match.
it is 100% the players fault(not previous players). This is not a complicated process. Both DOA and MKX
practice this method. It is less of a headache for the masses.
