management under file

Good morning

I would like to know if with OMV7 it was possible to administer the subfolders?

currently I manage to administer only the parent folder I would like to administer the parent folder and the subfolders. I am attaching an example via the photo with user 1 and user 2 I would like user 1 & 2 to access the parent folder "My_site" however the subfolders I would like to put restrictions 'user1 access user 2 no access, user 1&2 access full, and and user 1 reading and writing user 2 just reading

this is possible, do you have a little tutorial? currently when I try even by creating a folder via a parent folder on the server the subfolder does not take into account the administrations or appears in parents
