Advanced Fusion training course?

I briefly mentioned this in another comment but wanted to ask the question here. Last year, we talked with Adobe's training folks about developing a curriculum for an advanced Fusion training. This would not be a training which would happen right after the initial Fusion bootcamp. Rather, this would be a course one would take after a few months of using the tool. 

Obviously, you cannot cover everything within one bootcamp. Heck, you can't do it with two. But there are many things which most Fusion users don't know that they don't know until they're trying to build something...and they just can't figure it out (without having to engage Adobe consulting). 

I can think of a few things off the top of my head right now--advanced use of the HTTP module, work with arrays, custom webhooks--which would be useful for users to receive instruction.

Also...we need more instructional materials on Experience League (which is a separate issue). 

Is this something which is being worked upon?
