Hi Mike, 

At this time, exporting the bundled items is unavailable in QuickBooks Online. You'll need to enter them to record manually. 

Also, you can import the products and services through excel file to your other QBO company file. Please check this article for the steps: How to import products and services from Excel.

You can also send feedback to our Products Developers Team. This way, your suggestion is analyzed for future product updates. 

If you need further assistance, please know we're here to help you.
