title: Teamcity pass parameters between different builds (different build configrations)
body: <p>I'm using TeamCity Professional 2020.1.2 .
  under a project I have multiple build configurations.
  what I want to do is generate a random string in every build of build config &quot;A&quot;
  and override it every time, build config &quot;A&quot; runs.
  Then I need to use it somewhere in build config &quot;B&quot;</p>
  <p>I know how to pass variables between build steps, but I don't know how to do the same between different build configurations.</p>
  <pre><code>echo &quot;##teamcity[setParameter name='env.path' value='/sample/path']&quot;
  
  </code></pre>
  <p>I thought meybe there should be a global parameter registry which every build can read and write from.</p>
