I'd like to request the ability to control custom field permissions based on user roles, with two options:

Edit restrictions: Allow admins to lock specific custom fields so only users with the appropriate role can modify their values. Other users would have read-only access.

Visibility restrictions: Allow admins to hide specific custom fields from certain user roles.

Ideally, these permissions could be configured individually for each custom field, giving admins more control over who can view and edit information.
