coppermine is an app that is used world-wide, but the printing services only operate globally. What would be the point of a feature that allows you to order prints from a German print service if you reside in the US, for example? As this depends on regional settings, it's impossible to do. Additionally, the number of available printing services in a coppermine package would mean setting up a bias and name some companies.
Such a feature will definitely not go into coppermine's core, however it would be welcome to be posted as a user contribution, preferably as a plugin.
