eSignatures on User Defined Form

Summary

Is it possible for user defined form to contain 2 eSignatures, obtained at separate steps in onboarding process.

I have several user defined forms that required both the candidate and HR rep signature.  Is it possible to have 2 different eSignatures on the same form?  The form would start with the candidate and then be routed to HR for signature and completion, via onboarding steps.   When I tried this, the mandatory eSignature works for the candidate, but the candidate's eSignature fails when the HR team attempts to complete form.  I've tried to make the field not required and text only for the HR version of the form.
