Control GI Prepassing in Cinema 4D (R13)

Hello all,

I'm curious if anyone knows how to control prepassing during rendering-to-picture-viewer with Global Illumination. Meaning, rather than having my GI prepass all of my animations' frames before going back, would it be possible to have it calculate light particles prior to rendering the scene, one frame at a time?

I am using IR filter (Mixed feelings about QMC) with 2.0 gamma.

My work around is to simply render small chunks at a time, but I feel like I am missing something.

Thank you in advance.
