仅在新的失败构建上创建TFS工作项

I've seen the post about disabling work item creation on all failed builds, but I'd like to have TFS only create a work item on the first failure. We have a very complicated legacy system that involves VB6 COM components and frequently have build failures on the build server that track back to some funkiness VB6 does with binary files (frx, ctl, etc. -- if you haven't had to deal with that in a while, you don't want to). The only way to resolve those issues is to try to make updates on a developer machine, then check in the files and run the build again (since the build doesn't fail on the dev machine). So we may have three or four (or more) failed builds before we get a success, which means we'll have three or four work items to close out.I've seen the post about disabling work item cr
