Single Signer - Multiple Signatures, each with its own respective signing date

All,

How do I use field tags in Adobe Sign to (i) require multiple signatures from the same individual on the same document, and (ii) automatically fill-in a separate date for each signature.  To be clear, I want to force the signer to click on each signature field, so that I can be sure he/she is signing deliberately.  I'd also prefer to have a separate automatic date associated with each signature -- in case he/she signs over several days.  

The default mode for Adobe Sign doesn't seem to permit the above.  It seems like all signature fields that are associated with a single email address in the same document automatically get assigned a common signature, once the user has filled in the first one.  I'd like to overcome that default mode.

Thoughts?

Thanks, Dave
