Hey again, rgerger. 

Unfortunately, that's the only alternative. However, perhaps you can include both the Work Order numbers and the notes in the memo section but separate them somehow, maybe with a " / ". I do agree that would be a useful feature and addition to the product, so for that reason, I'm going to suggest this to our product development team, they can review it and consider adding it to a future update. You can keep an eye on our blog, this is where you'll find notes on changes made to the QuickBooks product. 

Thanks for the suggestion and if you have other questions, I'm just a few click away. Have a nice Thursday.
