Signature on multistep approval process

Hi,

We currently have a business process which has two step approvals. The requestor submits the hard copy of form to Approver 1, Approver 1 signs the forms and passes on to Approver 2 . The process is completed when Approver 2 signs the form.

We are experimenting to make this process online by using Interactive forms and came across some questions which are not so detail in SAP Help. I tried to search previous posts but many were unanswered.

1. Can we extract signatures from the Form like data ?

2. How is it possible to render the Form with a signature if it is already signed? e.g. When Approver 2 logs onto his screen, the form should show that it was already signed by Approver 1 along with the signature details

Any help is highly appreciated, thanks!
