I'm using this MultiDatePicker to allow users on my project to select multiple days on the calendar.

My problem is I want to allow them to select specific week days and then select a date range and by doing this select those days within the range.

Example: Select all (Monday) and (Wednesday) from (September 10 2014) to (August 10 2014) and when the user clicks a button or something, all Mondays and Wednesday within September 10 and August 10 get automatically selected in the full-year calendar's days.

Any ideas on how can I achieve this?
