How to get data from a smart form and data from the Requisition to auto populate on the PO

I have a smart form built in our Dev 5 environment that I will attach screenshots of. I am needing to have the additional information fields from the smart form to show up on the PO and be filled out. I also need the attachment on the requisition to be attached to the PO. I thought this would automatically transfer over but it has not. Lastly, on the smart form is there a way to make supplier site default to Manual Purch? I will drop some screenshots into a word document and post to this ticket.
