Customize Quiz Review: Need Results by Quiz Bank

Each section of my course has a related random draw quiz bank, and all of those quiz banks together make up the graded quiz at the end of the course.

My client wants there to be feedback at the end of the graded quiz that summarizes how they did in each course section (that is, for each quiz bank) so learners know which sections of the course they need to review. I'd also be providing a summary result number for all quiz questions together on the results slide, of course.

I'm assuming this would involve creating a custom quiz review slide and using variables and triggers - but it would be a huge help if I didn't have to reinvent that particular wheel and could get an idea of the steps to take.

Does anyone know how to set this up? Thanks for any help you can provide!
