Is there a way to remove the current build history?

Hi All

I've been trying to get teamcity to build my project (see this thread: http://jetbrains.net/devnet/message/5244190#5244190) and now I have a lot of items in my history that aren't really part of my build history (mostly partial-builds etc. etc.). Is there a way to clear all these results + logs etc. from the memory of teamcity. I don't really care about keeping the results.

Thanks

Patrick
