Event Registration - Tiered Pricing for additional registrants

We offer tiered registration pricing for some events - such as our upcoming summer Vacation Bible School.  The event price is $25 first child, $15 for each additional child.  Unfortunately, KidCheck does not currently offer a tiered price option in event registrations.  I understand once the child is registered we can edit the price; however, this is confusing for the guardians who are registering their children and additional work for us with potential for mistake. 

Please let me know if this could be an enhancement to KidCheck.  Any advice you have in the meantime would be helpful.
