[Koha] creating a new subscription for a journal with continuous numbering

Hello, I am setting up serials subscriptions in Koha and have a question about creating the prediction pattern for a particular title. The Journal of the American Statistical Association comes out quarterly and the volume changes every year. However, the numbering is continuous. The copy I have in hand is Volume 104, Number 486. Can someone explain how to create a custom prediction for this title? Thanks, Adam Adam Balcziunas Serials & Reference Librarian Landman Library Arcadia University 215.572.2842
