More Flexible and Automated Changes with Date Range Comparisons

Description - Have the date range comparisons update to align with selected dates for current time period regardless of date granularity and without need to go into the settings and adjustment comparison time periods 

Why is this feature important to you - allows for fewer and more flexible reports to be built for the team

How would you like the feature to work - the custom time period is based on both the first and last date in the selection and updates automatically as the date range is updated

Current Behaviour - locked to the start date and requires going into the time range settings and adjusting the rolling time periods (much too complex for basic business user)
