When using the Excel (Business) connector you can currently select the "File" that will be used for the "get row" action at design time. This works fine if the spreadsheet already exists and you want to continously reference it when you flow is initiated. However, if you wanted to set up a document library that contained an Excel spreadsheet as a template that a user could edit and save to the library to then have a Flow take action on, you can't. Specifically, I would like the ability so that either through a manual trigger or when the spreadsheet is new/updated that the spreadsheet file (name, link, whatever is needed) could be used as a dynamic value on the "get row" action so that I could just grab a cell from the newly created spreadsheet and use it in the rest of the flow.
