Attaching more files to campaign after they have been sent


New Member
We'd like to attach few more files to an already ran campaign. The subscribers would need to get a notification that a new files have been added to their tenders that have been invited to and they can check them by log-in into the site.

We have already extended Campaigns as TenderController and make all our customization there. I'm also thinking of extending of Campaign model to TenderModel and make the campaign editable even after it ran. I'm also thinking of modifying the campaign behavior so that campaign sends a different message when it ran the second time. Any ideas on how to achieve this?
