archive planbook

I would like to clean up the home page by archiving my old planbooks. I moved to 3rd grade after teaching 1st grade for 3 years, and having 2 years of lesson plans on here for that. I also created a test planbook so I could show some coworkers some of the setup process, but I find it unnecessary to keep it on here. I would like to have a way to only see the current planbook I'm working on.
