how hard to code custom auto-replies in support manager?

[Rocketz]

Open to everyone who'd like to answer this. How hard would it be to code in custom auto-replies (and option to enable / disable auto-replies)? 

The more data that gets migrated into Blesta, and as departments get used, there's a big annoying problem, and that's auto-replies. Not everything is a support request. 

So how hard and how long would it take to code what I'd like in?
