Training on Sage Report Designer

SUGGESTED

I've used Sage for years, and have a tiny bit of self taught experience in Report Designer. I'm looking to plug the holes in my knowledge but can't find a book or anything like that online. Can anyone recommend a good way of getting training in report designer?

I spoke to Sage before when I was looking to build a new report and they wouldn't tell me how to do it myself, they wanted to build the report for me. That's no good when I want to change it later though.
