remove attachments from email

This is an enhancement request.

I would like to be able to remove attachments that I have downloaded from emails and save the email without the attachment using the browser based email functionality.

This would save space but leave the email. Right now the only awkward way to do this is forward the email to myself without the attachment, and delete the original email. This screws up the date stamping of the email in question. 

Thanks
