How do I create AR payment term that specifies end-of-month plus X number of days?

I need to create a variety of payment terms that are some number of days after the end of the month of the invoice.  So, for example, let's say the invoice date is 08-JUN-2015 and the terms are EOM+96.  I want the due date to be 96 days from 30-JUN-2015.  Does anyone know how I can accomplish this with standard functionality?

Thanks,
Mary Jo
