Thanks for joining this thread, @BobbieCole. 

I appreciate your thoughts on this matter, so I would like to provide more information about it as well as a workaround. 

I know how beneficial it is to have the feature you need to complete your task. However, the option to merge two item receipts in one bill is currently unavailable in QuickBooks Desktop (QBDT). 

To request the addition of this option, I recommend sending feedback to our Product Developer. Rest assured that they are bound to improve the program's capacity to meet your needs. Here's how:

1. Open your QBDT company and click the Help menu.
2. Then, choose the Send Feedback Online option.
3. Next, select Product Suggestion.
4. From there, enter a brief description of your feedback. Example: Have an option to combine 2 item receipts into one bill in QuickBooks Desktop.
5. Once finished, sick Send Feedback. 

In the meantime, you may want to follow the shared workaround steps by @AbeEd to combine receipts into one bill. You can also, create separate bills for each receipt. 

I've included this reference to further guide you in managing your Accounts Payable transactions in QBDT: Accounts Payable workflows in QuickBooks Desktop.

Just in case you'll need to have a list of transactions assigned to a specific vendor, you can run the Transaction List by Vendor report. Let me guide you on how:

1. In your QBDT company, navigate to the Reports tab.
2. Next, hover your cursor to the Vendors & Payables section and choose Transaction List by Vendor.
3. Once opened, click Customize Report.
4. Filter the report based on the data you want to display.
5. When finished, select OK and click the Refresh option.

Please post a reply below if you have any other concerns about managing your bills in QuickBooks. I'm always around ready to lend you a hand. Take care always and have a good one.
