Design Question - 1 or >1 Pages Driven By 1 Database

Quick question about database design in Wix. I have a Collection established that drives data for a table that works well. It has 6 columns defined, all of which are used to provide class schedule information. Now I need to create a page to log payments. One of the form fields on my page will contain a “category” drop-down. I’ll put the data in the database for ease of use and maintenance.

My question for you all is thus: design-wise, would I be better off making a new Collection for the handful of rows I need, or just add the 5 or so fields to the existing schedule table?
