Quickly add/remove/change models for pages that are linked to more than one model

alexander.wolman

Currently in the UX manage models area, you can quickly change the model connected with a page if that page is only linked to one model (green X). If that page is connected to multiple models you can't (red X).

Propose increasing functionality to allow quick add/remove/change options in the UX manage models area.

We regularly bring backup models online for users and have to painstakingly link the models to each UX page one by one. It can take up to 6 hours. This improvement would dramatically improve things.
