(Quickbooks)Payment from multiple sources for a single job

Hi,

I am using Quickbooks for a small business (learning center). For some of my students part of the tuition payment is done by parents and part by a government agency. I was wondering how can I apply payment from multiple sources to one job. My first thought was to creat one customer called "Government Agency" and list all students (each registered in different subjects) as jobs of the big customer, but this seems to be a very rudimentary way.

I was wondering what is a better way to handle this case?

Thanks
