Need filter for "Is buddy of current user and is current user"

I'm working on a project to create a view of content created by a user's buddies as well as the currently logged in user. What I'd like is an additional filter in the buddylist views to "show all content from the users buddies" as well as "all content from the current user". Because the filters are "AND" in the view, I can't combine the filters. I tried using Views Union to merge two separate views (one with buddy content, and one with user content), but Views Union seemed to have some weird caching issues and was not 100% accurate.

Any thoughts or suggestions on the best way to add this filter as an option to the buddylist filters?
