Cue drum loops in order but waits to play until the downbeat

I have a few premade 4 bar drum loops on each pad. I have it set that when I hit A, then B that A stops playing and B starts playing. I want to have B start playing at the end of the 4 bar loop instead of now where it only stops and starts playing exactly when I hit the pad instead of it doing it every beat or bar in accordance to the tempo of the song. This is on the SP404 mkii.

Any ideas?

you either sequence it or play it in time with your hands, there's no launch quantization as in ableton live on the sp, it is more like a playable instrument from this point of view.
