Conditional Smart folder actions

I would like to have template/training folders that when I drop an email into it if it doesn’t already exist in a folder action that a script runs and adds the domain to that condition list.

Is that possible?

Example Google has a five-category inbox (Important, Social, Updates, Forum, Promotions).

In MailmMate I have set up smart folders that set on several conditions

Mailboxes (Any):
All Messages
Mailbox_Name->Promotions (IMAP Mailbox Folder).

Conditions:
ANY: From->Domaincontainss example.com
