When posting, make the default city the current user location city

Hello!

When posting a new place or cpt, how can we make the default city that populates in the form the current user location city?

For example if user is in New York, user see New York as the default city in the form when posting.
If user is in Miami, user see Miami as the default city in the form when posting.
Etc

Please see attachment.

Thank you!
