When sending an agreement to a company for signing, they frequently need 2 signatories, and in most of those cases, we don't know who the second signatory is when we send the document for signing.

So we need the signatory to be able to nominate a second signatory.

This is a common legal requirement for companies signing agreements under Section 127 of the Corporations Act in Australia.

I am aware that a workaround for this is to know the second signatory's email address and include it, but often we won't know it.

This feature would give High Level Documents a useful feature that Docusign and Adobe Sign don't seem to have (at least from what I gather from chatting with their sales team).
