The ability to change the order that data is listed in the details

If this is already possible by editing an XAML file or something, can someone please post that information here?

Anyways, I created a custom field for N64 games that use the Expansion Pak. I'd like that field to go on the very end of all the data that is listed, that way when it begins auto scrolling, you can read that extra information. Currently, the field is auto sorted before 'times played' and 'last played.'
