Make membership payment mandatory for child accounts if integrated billing enabled in portal

Currently when integrated billing is enabled a new member creating an account and selecting a membership has to pay for the membership at that time, even if billing through the portal is disabled. Once you know this, I guess that's ok. However, if you have done this and then go to add a child (not under a family membership, but adding a child with their own membership), CR allows you to add the child, select a membership, and finish the process without paying for the membership - and then the child account is tagged as expired because the membership is not paid. 

CR should either 1) force the payment for the child membership, or 2) have a very clear and prominent warning stating that unpaid memberships will be tagged as expired, meaning not able to signup for events or book courts
