well, if I'm right (correct me if i'm not), when you're routing SSD you can see 2 channels for each element (2 for kick, 2 for snare,..). So you want to rout the kick for example on 2 different channels tracks (not assigned yet), then you pan each one hard left and hard right. Next you can trigg each one (the L panned with the SNARE04_L and the R panned with the SNARE04_R if you want the snare4). The last step is to creat a new mono group track and rout the two (L and R) into this track. Finally you could apply EQ, processing, etc.. on this last track.
