Re: Introducing "Request sign-off" - an approval flow that requires no set up

Dan Foxley - No. pointing out the "for a selected item" is the trigger for the Flow which allows the user to select an item and use the Flow menu to start the Flow. Populating your custom "Approval History" column is simply using a "SharePoint - Update Item" step in the Flow after the approval step. You will see the approval dynamic content available to select (to update the column value). If this is not clear I'd suggest just researching more on the "creating a Flow with SharePoint" first.
