Write access only to specific source or scope?

[verybadsoldier]

Hi everyone,

is there a way to configure access control to give a user write/edit access only to a specific folder or scope?

I understand the current access control system so that write (and edit) access is given to a user only globally and it then affects all sources and directories a user can access. So, the sources and scopes are defining if a user has access or not and the type of access is only assigned globally in the user management for a user.

Is this correct or is there a way to give more fine grained delete/edit file permissions? So, you could say "user A has generally only read access but he has write access to source XY".
