Add additional signers and documents to an existing Signing Session by sending a list of documents and or signers.  When adding documents, you can specify the location (sequence) of the new document in the Signing Session document order. When adding new signers and specifying SignerRoles, roles currently assigned to an existing signer will not be add and an error message will be returned specifying the signer and the role.
