My scenario:
I have a calendar datapage in the "week" view. I have a button that lists records only in "current week".

I would like to have the option to filter my listed records by the week selected on the calendar. When I navigate to a specific week in the calendar, there is a parameter in the URL named "cbCalendarStartDate".
We could use this parameter date to filter the list by something like "Same week as: [@cbCalendarStartDate]". Currently there is only options of:
Current Week
Current Month
Current Year
Previous X Days
Next X Days
etc...
