title: Is it possible to reset a Jenkins build parameter such that 'Rebuild' or 'Retry' uses the new value?
body: <p>I have a job with the parameter <code>PULL_REQUEST_ID</code> that defaults to <code>*</code>. It's used to get the branch of a Stash pull request. During the build, the exact pull request id is known. I can reset the <code>PULL_REQUEST_ID</code> environment variable but when hitting 'Rebuild', the <code>PULL_REQUEST_ID</code> parameter is still set to <code>*</code>. Is there a way to get Jenkins to 'remember' the reset value?</p>
