Is it possible to use loops longer than 1 bar in Nerve? If so, how?

Tried googling this and searching the forum but couldn't find what I need. I'm just wondering if its possible to use drum loops within nerve that are longer than 1 bar long. For example I have a bunch of garage/house loops that are 2 or 4 bars that I want to drop into nerve and process, but it currently it only loads the first bar.
Is it possible to process loops that are longer than one bar and if so how?
Thanks!

Loops are limited to 16 slices, the idea is to have a bunch of segments for source for making new beats, not as a loop player.  

 you can in theory load a 2bar loop and use half-speed timing, but I'm going to answer "no" for completeness.
