How to set up selectable email recipients of selected attachments? (email integration)

Hello, I have an item where i am separating attachments into various file columns. From here i have columns of recipients id like to send this information to (using text columns to write in email addresses).

What id like to be able to do is select which recipient will receive what file column as this differs in each project-without having to manually adjust the integration automation below each time.

Is there a better way to achieve this?
