Change dates in View access

[#1]

With the recent move to View, Duplicate and Edit access levels it would be great if users with View access could change and interact with the date range. While they can interact with filters/drop downs this doesn't work as well for dates as often users what to look at specific date ranges after a change, sale, weather, event etc. We can't always have pre-programmed all the options they'd want to look at into a filter. This wouldn't alter the dashboard so would still be a view level of access.

Even better would be able to lock or unlock date ranges for view access.
