title: tfs 2013 incremental build number across build definitions
body: <p>I am wondering how you could implement an incremental build number that is shared by several different build definitions.  For example, I one build definition for our staging environment which has a build number of say 15.3.6.1.  I then queue a build for production, different build definition, I want that build number to be 15.3.6.2 instead of 15.3.6.1.  Is this possible with TFS 2013 builds, whether out of the box or through an extension?</p>
