Enabling Multiple Signers on Web Forms and Disabling "Final Document Signed" Email

Hi, I currently have the Adobe Sign Small Business trial. Before I subscribe I need to make sure that the software will meet my needs, and in its current form it does not. I want to test two features 1) turning off the final signed document email notification to everyone and 2) allowing multiple signers for web forms. I spoke with several specialists through the support chat and was told that these features can be disabled/enabled via backend tools if requested here. Can someone assist me with this?
