[Mailman-Users] Add a footer to each digest entry that will allow a reply

[Steve Nospam]

I would like to add a footer to each message in the digest that will allow the recipient to click and post a reply with the correct subject, etc.  Is this possible?  My searches haven't produced any useful hits.

I have subscribers who only want to get a single email each day but they would like to answer some of the postings.

Thanks!
