Adding content to a page, but not printing that content?

Hi, I have a wine list menu in InDesign, and another person on our team wants to be able to add notes regarding inventory/stock, but obviously not print those notes for when we distribute to customers. Is there a way we can do that without having to have two versions? I thought about duplicating pages, and then hiding them, but I'm not sure how that would work. Or is there a way to create two copies, but the copy updates based on changes to the main file?
