It would be amazing if Smartsheet could allow for form information to update existing rows on a sheet. An example use case is quality control, we want the task worker to fill out fields related to a task he is working on a project. The worker is in the field and sifting through dynamic view or project reports is not a desirable state and has less functionality. Ideally, the person filling out the form would select the column identifier - this would be a dropdown selection. Then they would fill in the cell data that would flow to fill in the existing/corresponding row on the sheet.
