For each participant type we can choose what registrant info we want to collect. But if we say address we get Street 1, Street 2 and Street 3. No one ever fills out Street 3 - unnecessary. Also only allowed to pick phone, not home phone, work phone or mobile phone. I can add another question and link it to mobile phone field but then it is not part of the registration fields on the form. Need more control vs the grid we get on step 7.c.
