Can you submit PPT renders to backburner?

Can you submit PPT renders to backburner?
The reason i ask is because i have set up a scene that it slightly strange in that it renders differently (and how i want it to with sharp shadows) in PPT mode, but not with QMC / LC or LC/LC or IRM/LC or any other way.

Weird i know, but i’ve got 36 images to do, could I submit renders to backburner as PPT, would i have to wait for them to finish and thus calculate the amount of samples needed for acceptable times, or could i submit them as PPT, and cancel them through backburner in the morning?

Would they save properly?

actually doing some tests QMC / LC does return the same results, but i’d still like to know if theretically you could submit renders to PPT via backburner, and how/if they would be saved.

simplest answer, try it. I dont know if it will save the frame, most likely it wont, unless you render in to vrayimage.
