How to prevent Line Manager from creating their own document records

Summary:

We have configured some documents as 'Restrict Create' and 'Restrict Update' as employees should not be able to create or edit them but have added an exclusion for the Line Manager role as the Line manager will need to create and update them for their direct reports.

However, this has meant that the Line Manager can then create the document for themselves and make changes as they have the role that lifts the restriction.

For example, Line Manager should be able to create and edit an appraisal document record for their team but should not be able to create or edit their own, but it seems that are still able to do this as the restrictions don't seem to be able to work out if the exclusion should apply to their own or their direct reports documents.
