add/update/remove records to Table2 from input on Table1

The changes in Creator 2.0 look great! However, I still can't figure out if I can do what I've wanted to do from the start:

Have a table of Contacts

When I get to the Phones fields/section, have some way of adding records to the Phones table which are children of the Contact being entered.

I see no button object available for this task.. nothing in the lookup seems helpful either.
