Hi DexDexter. Thanks for joining the discussion. Unlike QuickBooks Desktop where you're able to add multiple subtotals, QuickBooks Online doesn't have that option at this time. I know how handy this would be, and how important it can be for your business. I'd be happy to pass your thoughts on to the product development team, and I'd encourage you to submit your thoughts to them as well. You can do that by clicking the Gear icon > Feedback.

If you're in need of any additional assistance, please reach out to our tech support team. 

Cheers.
