title: Build number Format in TFS
body: <p>I want to include the version number of a specific assembly in my Build defintion number format, for example, instead of having the default [$(BuildDefinitionName)<em>$(Date:yyyyMMdd)$(Rev:.r)] i want to have something like [$(BuildDefinitionName)</em>$(Date:yyyyMMdd)$(Rev:.r)_Major.Minor.Build.Revision]</p>
  
  <p>Is it possible? are the macros customizable?</p>
