I am working on a process where an approver wants to be able to use the direct approval option however still insert their signature onto the form. I have direct approval setup, I had the user create a signature under their profile and save it. However when they get the email and hit approve the signature does not insert. On the signature variable I have the "use the default signature for the current user" checked. 
Just wondering if anyone else has done this before and if it can be done... Add the signature from an email approval.

First time using and testing this out.
