How do we keep invoices sorted by Invoice Number instead of it's seemingly-default "due date"/overdue?

Thank you for reaching out to the QuickBooks Community, ambbwc. As far as the due date and overdue for the invoice that is how the system was created setting that as the default. However, you can sort the invoices number by select that triangle as seen in the screenshot below.

Also, I would recommend submitted feedback to our Product Developers. They look forward to seeing your suggestions to enhance the system. Here's how to submit feedback:

1. Go to the Gear icon at the top and select Feedback.
2. Enter your product suggestions and choose Next.
3. Select Skip and send message.
4. Choose the category from the drop-down, and click Send Message.

Leave me a reply below if there's anything I can assist you with. Have a nice day and take care!

Thank you, I appreciate you confirming that it is not possible. 

Yes I am aware I can click the triangle to sort by Invoice Date. But I *always* wanted sorted by Invoice Date, and I do not want to have to click that triangle every single time I am in the Invoices view -- nor do I want to continually explain to other people using our QBO file that they too must always click the triangle in order to sort by Invoice Date.
