Just throwing and idea out there that I think might be neat to have.

I know this can be done in tops but sometimes it would just take a bunch of time to set that up.
It would be pretty cool if there would be an option on the rop and or file cache node to save the frames independently from in each other and with multiple instances of houdini. Probably not really viable but it would be really cool to have a quick option for that.

Again just an idea
