Basic configuration for this case

I have this configuration (G: Group, U: User, SF: Shared Folder):

G1 (Quota 150 GB)
...U11
...U12
G2 (Quota 50 GB)
...U21
...U22

DISK (400GB)
...SF1 (R/W only by U11)
......SSF11 (R/W only by U11)
......SSF12 (R/W only by G1)
...SF2 (R/W only by U21)
......SSF21 (R/W only by G2)

How can I implement this configuration on OMV?
