Feature Request: allow REPLY-TO field in mailing profile

When emailing documents it is possible to choose which mailing profile to use, so I was considering making a profile per user... or would it be possible to have the reply-to address picked up from the users profile?

The reason for this request is that I send email out of our gateway with a FROM of a registered domain, but that address is purely used for scraping off mailed in documents. Whereas (just about) every time I email out a document people reply back to that email. If I could have a "reply-to" address I could mail out of the registered domain, and then people could reply to any email address, such as my gmail account that gets checked more frequently (potentially).

This could either be an optional field or a checkbox that when activated would expose the field (first one being adequate, as it would only be usd when settin up the relevant profiles).
