How do you maintain a requirement for electronic signatures when approvals are re-distributed?

We are using Workfront as an Approval tool and want to use the check boxes that require login and require decisions to be electronically signed. We want to send the proof to administrators on our regulatory, legal and brand teams and have them redistribute the proof to other team members for approval based on area of expertise and availability. The problem is that when we forward from inside the proof, the options for require login and require decisions to be electronically signed don't exist.

Have others had similar challenges? How did you solve the problem?
