Allow users to specify a default series for PPA browsing

As I asked in question #895885, I have several PPA's in me sources.list and while I can ID the source in Update Manager thanks to recent updates when I go to the PPA package list (I have all of the ones I use bookmarked) I have to manually limit the selection to the series I use (karmic). Is there a preference I can set to default to a specific series when browsing PPA's? It would be a great time saver if it's available.

For example, I could go into my LP profile and have a screen (details perhaps?) where I could specify that I could specify which version of Ubuntu I use, similar to how the UForums give me a chance to specify my distro and flavor. Once this selection is made then when the server is asked compile a page for a specific PPA (main PPA page if not just the package details screen) it would consult the database and see that I have specified the "karmic" series and default to showing me packages in that series rather than showing me all packages and offering to let me filter the packages by a specific series.
