Restrict column edit on SPECIFIC group

At the moment, the permissions that the admin is allowed to set is too simple. For example, One one board, I have a few groups. In the column, I would like my employee’s to be able to make edits to one column in a specific group, But in the other group, I don’t want to give them access to edit. At the moment, When you lock one column, it locks the column on all the groups. IF we can explain on this and be more specific on what we want to lock. We would be able to create a more effective platform.
