From reading the manual, the TimeFactor should work for your situation.  The way I understand it, there are separate left and right ins and outs.  The pedal is supposed to sense your ins/outs.  If you are using left and rights out, then you should get separate outs.  If you are only running one input (or even two inputs) with only a mono output, then the pedal would sum them at the output.  I hope this makes sense and I am not off the mark.  I would have thought somebody else would have chimed in on this by now.  I wanted to put my two cents in so you would at least have something to go on.  You should be able to access the manual on-line – check it out for yourself 😉
