Convert text field to enum

Whenever I work with someone to import their data, importing enums is a bit of a nightmare.
It would be amazing if it could be done in two times:
First I import via CSV as a text field.
Then later in field settings I have an option to convert that field into an enum. It should tell me that there are xx distinct value and ask me to confirm as this action cannot be reversed.

It's not something you need to do everyday but when you do need to import something, it's life-saving 😅
