MIDI CC 80 and MIDI CC 81 , Grup select

Can you here help with my case, in making a switch from sound A to B via group and using MIDI CC 80 and MIDI CC 81 as controls, but I want there to be a pause every time I want to move or have to sound first before one sound can move, in the default program of The contact can only change sound when MIDI CC 80/81 is pressed, and when released it will move to the previous group, so what I want here is that when MIDI CC 80/81 is pressed it doesn't come back until there is sound from the selected group. sound. please help me, thank you
