Create a Date widget that allows multiple date selection without reservation.

I am looking for a calendar widget that allows you to pick more than one date without blacking it out for future entries. I tried the reservation widget but I need to be able to choose the same date again. How do I accomplish this? 

There isn't any other widget, besides the Date Reservation widget, that allows multiple date selection.

I have forwarded this as a feature request to our back-end team, unfortunately, there is no estimated time-frame for a resolution, so if there is a progress in the future with this request, you will be notified via this thread.
