Bouncing Multiple Outputs at once

[Peter Project]

Does anyone know if there's a simple way to bounce multiple logic outputs at once?

Currently I'm bybassing my stereo output and have 8 stereo outputs feeding a protools rig on another computer which I'm printing to.

But sometimes if I need precise accuracy as to when the bounces start (rather than waiting for sloppy MTC to lock in PT), I'll just manually bounce out the various master outputs through logic,(1-2) (3-4) (5-6) etc. I'm wondering if there's a way to just press one button, and have all the outputs bounce out 8 stereo wavs at once rather than manually bouncing each once.
