Can a Smartsheet form submitted auto-populate PDF then triggers DocuSign

Hi,

I am trying to deploy a reimbursement system for my office.





Once a person submits a form via smartsheet, I need to have a PDF pre-filled with all of the info including the ones that will be linked to other cells. 

Once the PDF is prefilled, I will need it to go thru DocuSign for signature. Once the user signs I will need to have smartsheet trigger an alert/change status of the row by "ready for submission".

Would love to see if this is doable.
