We would like to be able to limit who can change the Expiration Date and Address Check Date in the patron registration workform. Off the two, Address Check Date is most important as this is what we use to make sure patrons are updating their information regularly.

These are configured in SA and are set system wide yet staff continue to change them.

If I remove the 'Patron registration: Modify permission' for member library staff, they won't be able to change other fields.
