Then I ask them to fill out a table with their milestones directly into Coda since the form is not so useful when I don’t know how many rows may be needed.
there is an option on the forms to allow for multiple submissions. Go to “Edit Layout”, then under “Confirmation”, toggle on (blue colour Eye icon) “Submit again”.
Hope my approach can help someone too.
