Is it possible to provide fine grained control (folder level/file level) for a given volume?

I have two SCIM integrated groups who have read volume access at the catalog level, but those two groups need different permissions on a lower level. Preferably at a folder or file level within the volume. 

Volume:

(Top level)

• landing/

(Inner level)

• • landing/PDF (group 1 needs access only)
  • landing/CSV (group 2 needs access only)

Is it possible to achieve this without having to mount the inner levels as a top level or creating X schemas? Any recommendations are highly appreciated.
