Color Jitter map not propagating to particles in 3ds max

Hi, Experienced 3ds Maxer, but new to Arnold.

I'm looking for a similar feature to Mental Ray's old 'multi-map shader' map that you could use to alter objects and particles randomly or by mat ID. Example can be seen here: https://www.youtube.com/watch?v=a8J42lmWRRs

I've tried to use Arnold's 'Color Jitter' map explained in the help docs: https://docs.arnoldrenderer.com/display/A5AF3DSUG/Color+Jitter - but I am having difficulties getting it to see particles created in Pflow as individual objects. So Arnold is applying the same random color to everything in the particle group.

Someone else has posted about this issue here: https://forums.autodesk.com/t5/3ds-max-forum/pflow-and-arnold-color-jitter-in-3ds-max-2019/td-p/8199... - but a real solution was not found.

I am curious if there is a work around to this issue if I am wanting to use randomly colored particles and not primitives.

This question has been posted before and a work around has been provided here: https://answers.arnoldrenderer.com/questions/7547/pflow-and-color-jitter-1.html - however I am wanting to use different 3d objects as the particles with different face/poly counts. I understand what was described here and am grateful to use this workaround however it still doesn't allow shapes to have a unified color I am looking for.

Any ideas? - thanks in advance!
