Is there a way I can make teamcity build atomic

Hi,
I searched a lot on net but couldn't get the answer for this problem(May be I am bad with searches). Is there a way in teamcity-6, so that you can trigger a build for each commit in subversion. Currently if teamcity agents are busy, it queues all the changes done on a svn repository and run them at one go. What I want is to trigger the build for each commit. Is there any configuration settings in project that I can do to achieve the same ?

Thanks
