Is it possible to show the themes/plugins in the order of the different ProSite levels?

As it is, they are all mixed up showing the plugins & themes alphabetically, but it would be better to be able to show the user the plugins/themes they can actually use.

What would be better, would be to just show the plugins/themes that are available to the user on their current level.
