Hey there slda-mylabrador,
Welcome to the QuickBooks Community! Thanks for reaching out to us here. QuickBooks Online is a great tool able to help keep your books balanced. I would be happy to provide some information.
At this time, there isn't an option to have two class tracking categories for one paycheque in QuickBooks. I can see how having this option would be beneficial for you and your company. I encourage you to leave feedback by heading to the Gear icon and selecting the Feedback option. These comments are viewed and considered by our developers as they create new features and updates for QuickBooks.
If you have any other questions, feel free to reach out here.
