Hi @rh7,
As I explained in my previous reply, you have the option to customize the associations before you send an email but the automatic rules cannot be configured. It is currently not possible.
Yes, you can upvote the thread you linked. The product team reviews these requests based on popularity.
Right now, what you’re trying to achieve cannot be achieved after the email has been sent. You need to select the deal manually before sending the email.
Best regards
