SQL connector - dynamic environment variables

Hi all

We are using the SQL connector, but we’re having an issue when moving our app to production. I can’t see a method to make the SQL connector connect to our staging db in the bubble dev branch, but have the Live bubble environment point to the staging database.

Any ideas?
It looks like for standard API connectors that there is an option for personal plugins, but I cant see something similar for the SQL connector.
thanks
