Multiple select when creating Restrictions for custom roles

It should be possible to select multiple column names when creating a New column restriction for a role. Eg rather than create 5 separate rules for each column except Backlog to set “Task creation is not permitted for this column” one rule is created with 5 columns selected

This will reduce the time spend creating and managing rules.

Currently only one column is permitted per rule.

It would be great to edit rules too. I’ve created a large number of permissions and now need to set the flag for “tasks assigned to the current user” but I can only see how do this by deleting the restriction and recreating it.
