Include Column Description in Update Request Form or Form to Update Existing Rows
It would be incredibly helpful if the column descriptions were included in the update request form. We will request information from users who do not have access to the sheet and likely will be unfamiliar with the type of information that should be included in the column. Forms allow help text, this should also be a feature of the update request.
If the above is not possible, you should be able to send an additional form that can update an existing row.
