Webfig Design Maker, Interface security

Hi,

I’m having a minor issue - or rather - an idea.

I want to create an account for one of our customers where he / she can login to webfig and enable or disable one specific Interface. However - if I enter IP → Addresses (or Interfaces for that matter), then I can change the “Enable” checkbox and make it read-only. The problem is that this setting sticks for all Interfaces.
I want the user to have ether 1-4 as read only, and ether 5 should be possible to edit (enable or disable only).

Currently I am elaborating with version 5.18 but does anyone know if this has been possible in newer versions or if I am doing something wrong?

Cheers guys!

newer versions include many fixes for webfig and design mode. please try v6.7
