Most network listings have a semi generic format of the Product or Service, and you negotiate the finer details with the winning vendor. So you could customize your Laptops with a higher spec, or a winning Corporate Travel agent will have all the preferences in a Travel deal and their winning price should include this.

Or a Travel related deal might have additional fields to enter your preferences like a 5 Star Hotel with Pool view or ask you to suggest a preferred airline and membership number if you have one.

In short, don’t sweat this too much as you can always negotiate directly with the winning supplier on the finer details or upgrading your specs.
