Similar to how you can identically paste whatever data is on another page (ex. in Excel you can use formulas to reference data on one page to another) that will update whenever you update the original page. Are you able to do this for sections on confluence?
For example, we are trying to set up a portfolio page that has a view of all our individual program pages, but are trying to avoid copy and pasting each time there's an update on our individual program pages.
