Contact Tracing with TNEW v7 and Tess 15.1

With this new topic making the rounds-

How can TNEW V7 and the application, V15.1 support contact tracing? Ie- I buy 5 tickets - how do we collect contact info on the other 4 ticket holders?  I am most interested in how to do this with TNEW (but interested in phone sales too).  I am think custom form data??

Thoughts?
