Can I edit added website id in Piwik?

Hi friends,
I have added some of my websites in Piwik to track them. Now I want to reaarange the sites IDs. Means I just want to edit the order of added websites for some maintainability issue. Is that possible? OR I have to delete all the sites and again add them in desired order?

sorry rearranging order is not possible yet

Thanks Matt for your reply.
