Overall Product - How do you show?

Hey!

In our organisation, we have one big product and then smaller teams working within folders - we’re looking for a way to bring all of those together while keeping the current structure of folders to show the bigger picture of the Product in one file - but we haven’t found a way to continually update in a slick way when the product changes in one area.

I’m wondering how others have solved or thought about this issue?

Thanks,
Myles
