Feature request: rewrite subject of received emails

Sometimes, I receive emails with a (non-malicious but) misleading subject, or simply no subject.

This makes it harder to later find the email based on keywords.

Would it be possible to add a way to rewrite the Subject of received emails? Maybe something similar to HEY — Fix bad subjects without busting threads
