As a user if I am setting upsell products it would be useful to be able to see products where an upsell has been added so that I can focus on the remaining products that need to have an upsell product added.
At the moment the option is to add a custom field and flag if the product has an upsell.
The only issue with this is that it is manual and users may forget to flag that a product has an upsell so it would be good if this is done automatically.
