Tracy, this comment is from someone not in your Division (South Atlantic vs. California), so Division variances may prevail and you should validate with your ACS Staff partner. But...

Yes, sort of. The team members' registration fees would have to be made online as a team donation (unless the credit card holder want to post 15 transactions for 15 team members). A single $150 (or $10 times whatever number of team members) could be made online. To help with reconciliation, the dedication text from the "donor" could simply be input as "Team registration fees".

So, net: There's no option to pay registration fees online after the fact, but you can remit online via a "pseudo-donation".
