A handy thing about Google Sheets is that you can copy a tab from one Google Sheet into another Google Sheet.
This is especially powerful when you spend time building your own customized financial reports and budgets and decide you want to re-use them in another Google Sheet powered by Tiller's automated bank data feeds.
