Within Finale we have a feature that allows you to create product categories on the fly. To do this you will need to disable "legacy categories", see image below. Previously the categories needed to be created within Finale first in order to associate a product ID to a category, this new feature eliminated that requirement. The below video is a demonstration of using this feature.
Note: Please ensure to use the same case sensitivity when entering new categories or the system will create a new category based on "case sensitivity", i.e Apparel and apparel.
