Is it possible, using a Smartsheet web form, for the "File Attachment" widget to store the uploaded file to a designated Box.com folder? In other words, not as an file attachment to the Smartsheet row, but as a link attachment to the Box file?
Otherwise, the user needs to first upload the file to the correct Box folder first and then come back to the Smartsheet webform to share the link. Even then, it is not possible to share the link as a SmartSheet attachment to the row (since the File Upload widget in the Webform only allows local file attachments rather than the choices of Upload from Computer, Google, OneDrive, Box etc)
Thanks in advance for any ideas!
