Display Product Listing Default Sort Order

[DrByte]

What I want to do is list by Product ID and in Descending order.

That's not currently offered as a configurable option.

But if you leave the Default Sort Order switch blank, then it will sort by the Sort Order you've assigned to the products, followed by the product name.

ie:

Sort Order     Name
    10         Apple
    10         Banana
    20         Avocado
    30         Artichoke
