Ability to filter agent commission between Tentative and In progress Students

Agent commission feature is not really useful if we are not able to filter the commission based on student enrolment status. This basically pulls up all paid invoices, but invoice payment doesn't mean the student course commencement. we may have to refund the tuition fee if the student withdraws from the course before course commencement or gets a visa refused. 

it would be great if we are able to filter the invoice payment/ agents commission based on the student enrolment status.
