Admin Field - Change GoTo URL

It would be really helpful (and fairly simple) to add an Admin field that allows us to set the GoTo address after a successful subscription. Now I think it just refreshes to the same page (or the homepage)...

I have a client that wanted to offer a free report when the user signs up, and was able to do that by hacking the module but thats not a very elegant solution! I considered also just creating a simple add-on module to do this, but it seems like overkill for just adding a single feature.

Of course, I can do that if necessary... thoughts?
