Ability to update user role access/access to existing model features in a deployed model

Description of the enhancement required:
Ability to edit Users --> Roles->Versions in a deployed model.

A story for why you want the enhancement:

Currently during development cycles, using ALM forces you to treat user updates and editing the timescale for a specific version as a bugfix. This mean users have to wait for a minimum of 30 minutes to roll back development changes, create snapshots and sync the models in key reporting periods. If this has to be done a couple of times a day, to edit a timescale and reset it back this means an hour is lost for an activity should only take a few minutes. This also applies for user updates which means if someone needs access to an additional item, it also has to be treated as a bug fix which creates more configuration for admin users as well as time lost from a business perspective waiting for an update.
