Google Sheets under a team - Basecamp to Asana

Looking for input as we just migrated over from Basecamp. If I have a sales team and I have 3 google sheets - one to track sales close rates and one to track new clients and one to track marketing leads is there a way to have the google link under projects OR do I need to upgrade from premium to Business?

What do you mean? You want those 3 links to be available in the interface, next to other projects?
