Is your feature request related to a problem? Please describe.
When a range date is already selected, and we need to change only the start or the end date, currently we need to select the two dates.

Describe the solution you'd like
I would like to change the start date by clicking on the current start date, then click on the new start date
and no need to select again the end date.
Idem for the end date.
