Not as part of TT - that all happens server side.

In which case you have 2 options:

1. Process it client-side with javascript (not recommended)
2. Make each "addition" a new request, and store server-side

You could also do a combination with AJAX-type calls, which is probably
the best "modern" way of doing it, although it will be more complicated
than option 2.
