Thanks for sharing your idea here in the Quickbooks Community, @Dieselchick.

I understand how deleting multiple transactions in the register would be helpful for you. The product enhancement will be based on how popular a specific feature request is. 

I'll make sure to take note of this and will update you once this option is available for our users. In the meantime, I'd suggest visiting our QuickBooks Online Blog regularly. This way you'll be updated with the latest news and updates including product improvements. 

Please know that you're always welcome to post if you have any other questions. Have a good day!
