FOCUS FX to playing deck (Master)

hi all, sorry to dig up a matter thats been posted several times, but am a little lost

i gave up for now on the instant grat mapping, and am using tekkens ultimate FX

is there a way to focus the FX onto the playing master deck and not triggering it on both decks ?

ie: when going from A > B only trigger the fx on A and when going from B > A only on B

without having to turn fx on off the other deck
