[Forminator Pro] Generate unique meta_key

Hi Support-Team,

is it possible to change / modify the meta_key? It is very hard to map the select-1 to select-n form fileds to our needs. Especially by picking the fields in the E-Mail dialog.

What i was thinking about is something like that:
select-{unique-name} which i can set by my own.
I tested to overwrite the settings in the database, without success.
Looking forward hearing from you.
Best regards, Chris
