Custom field - Calendar period

Description - I would love to have access to a new field type to select a period of time (from - to)

Why is this feature important to you - To be able define a period

How would you like the feature to work - classical "Date Range Picker": 1st click: calendar popup, 2nd click: set start date, 3rd click: set end date, 4th click: apply

Current Behaviour - Currently two date fields have to be added where we do not have any kind of verification if the date selected in the second field is after the first one.

Regards
Lars
