Add second signature - non user

Hi

I have a document which requires a signature by the user and also a signature by the client on site. The client signature is a person who we may not know and therefore not have their email address.

The form is a service fault sheet which my engineers use when completing work. They will sign the sheet but the client needs to add their signature to approve the completed work. Currently when I add two signature boxes it completes the same signature twice.

I don't want to add another user to create a second signature as that would involve the client to check their emails which will add time to the process.

I am new to the software so I may be missing something pretty obvious.
