Character selection screen character order change

It would be nice to be able to change the order of your characters at the character selection screen.
For example, you want to reroll/change your main character, so you want him to appear first in the list. Same situation can occur after you bought a character at the marketplace and want him to be your main.

This feature has been implemented later in wow, i think it was cataclysm.
It might be not possible to implement this using the 3.3.5 wotlk client, but maybe it could be possible to implement via the website?
Thanks.
