Make updates to the Default View of the Release Gantt Chart

It would be great if users were allowed to make changes to the default view that everyone sees instead of being forced to save my own Custom View.

E.g. 

When I access the Default Gantt chart under a Product form the Quick Links – View Gantt it often loads one of my Saved Gantt Views. Next, I hit the Reset to default view option to get to the default Gantt that's viewed by everyone. Unfortunately, there is no way to make changes to this default Gantt so that all users see it when they access it. Some common use cases for this are:

1) Color bars by status - constant support requests on why their bars are a diff color

2) Hide assignees - we don't use this and it would be great if it could always be hidden

3) During Release planning our PMs update the common Gantt and tentatively spread Features out on the release for others to see. It would be great if they could do this in one place and everyone could see it. Instead, we have to create common shared reports/presentations where this can be viewed.
