Square Online Categories

Is it possible to get the categories assigned to items in the Square Online store? The use case here is I have a merchant with two sets of categories, the public customer facing ones in the online store and some backend categories (via Square Item Library) to route different items to different printers. Our app pulls in their Item Library data since that seems like the only data available, but the merchant really needs the customer facing online store categories. They can’t change the “backend” categories as they have it set up specifically for their kitchen production.
