WP-Media folder

Hello,
we have created different user groups (roles):

"group a"
"group b"
"group c"

in each group (role) we have more than 1 user.

Each user have correct access to the parent folder (we used the management settings for this "role")

It would be very useful to have a user (who is not an administrator) who can see all the folders of the various groups.
We checked the plugin code and in the code you use only the first role "array_shift($roles)" to assign the folders created.
It is a way to change this, do you expected this?

Is it possible with as-is plugin?
(if not) is an additional module necessary?
(if not) is it possible to manage this feature with workarounds? (in case: which ones)?

Thank you!
