Support for modified(thisPage) would be so helpful

On the bottom of each page in our doc, we would like display date time of last update and name of person who last updated the page. Since we are trying to put as much as possible in a single Doc, modified(thisDocument) is not very helpful in this instance. We’ve tried a few workarounds such as adding a table to the bottom of each page and updating the row, but all were unsustainable for us.

Thank you for considering.
