Access to multiple workspaces for LDAP users

Tulip workspaces is a great feature in Tulip to manage multiple sites.
But it can also be used to create segregation between Dev environment and Production environments. Or in life sciences GxP and non GxP apps.
Im trying to do all of the above.
One limitation I found is that one user can only be assigned access to only one workspace. For example if i assign an operator to our GxP workspace, they cannot access the non GxP workspace. But in reality the operator needs access to both kinds of apps.
Unfortunately tulip accounts using LDAP cannot assign users to multiple workspaces.
I would like to request this function.
