Supplier Certifications List

I’m looking to tie a list of certifications (e.g., an ISO Cert) and their expiration dates to suppliers in Epicor. I had looked at the Attributes field as a potential solution, but I don’t think there’s a way to tie expiration date to an attribute. Ideally, this would be something that could be easily queried, so we could generate a simple monthly report that gives a list of supplier certifications coming up on their due date, such that we could verify the certification is/will be renewed. Has anyone here done this without use of a customization?
