Relative Date Filter Between 2 Dates

When using Data Fields and adding a filter you can put a relative date filter that you can choose last, this, next / days, months years. It would be a good idea if the user could select a range of dates to show data in a specific range e.g Show data from 15th of one month to 16th of the next month for the last months set of data and this data will refresh until you use it on the next months date you have used as your filter so you do not have to keep changing the dates as it will be between two times in a month / across many months.
