Using StudioLive AR16's Super Chael for live backing tracks - is it possible?

Greetings! In the StudioLive AR16's review, it is said that this console "is great for backing tracks, click tracks, or program music."

Does it mean that I can somehow use it for playing backing tracks paired with a click-track, the metronome being sent only to the musicians' in-ears while the playback is both in the monitors and in the main mix?

Normally, I would create a stereo file with the click track paed hard left and the backing track hard right, and then use a splitter cable coming from a laptop to route the click and the loops into two separate chaels.

The question is: is there any way I can do that using only the Super Chael? Or do I still have to use the splitter cable and occupy one or two of the input chaels on the board?

Best regards, Kirill.
