Adobe Sign + Acrobat

Hello,

If I send a document for signing using Adobe Sign, if one of the people in the trail needs to sign it but then also wants someone else to sign it (who I hadn't added in to sign) is it possible for them to route it to that person (whilst still signing themselves)?

Thanks

Rachel

We use Acrobat Pro Dc and we use adobe sign, I incorrectly wrote docu sign as we use that nickname within our company. Please unlock the thread so I can edit it and it can be answered as I still need advice
