I suspect it's not based on a thorough read of the docs, but wanted to ask... I'll create a github enhancement request if the answer is no.
Basically I'd like to be able to direct the vfs read cache to dirA and vfs write cache to dirB as they have substantially different workloads/requirements on my system (lot of writes which it's fine if they go slow), fewer reads (but they need to be fast/performant)
The reading and writing parts of rclone are very intertwined. How would rclone know if it cached a file that you wanted it in the read only part of the disk and not the read/write part?
