Hi,
In the backend listing, when you display the product in "direct sub elements" and set the sorting on "order", you will be able to change the ordering number for every products in the page.
You can then click on the "save order" button (just near the "order" table title) to save the ordering.
To edit more products, just change the number in the pagination limitation.
