Is there a quick way to change date format in an entire form?

I have several date fields in my form. Is there a quick way to change all of them from MMDDYYY to DDMMYYYY or do I have to do it individually? Similarly with date separators and option field columns - can they be changed simultaneously?

Unfortunately, you'll need to change them all one by one, as each DateTime field is an independent item.

Than you for your understanding.
