Is there a way to delete mail attachments without deleting the text?

Hello! My mail is getting to it storage limit and one of the 2 solutions is to delete mails to make space.

The problem is that I can't delete mails becouse I recur to them periodically to check for user info, but I do want to delete their attachment files (since I don't need them anymore).

Is there a way to do this on all mails other than manually?
