Promoted Build plugin change the promotion status

[avinash....@gmail.com]

I am using Promoted Build plugin to mark the stable build. 

I have a scenario where i need to unmark the build from promotion. Any suggestion to achieve this ?

The idea is having am multiple builds with the promotion flag will make the deploy team confuse. So as soon as we get a new stable build, i want to unmark the build from promotion.

On successful promotion, build metadata file (build.xml) will gets updated with following status.

<statuses>
        <hudson.plugins.promoted__builds.Status>
          <name>Promotion</name>
          <badges>
            <hudson.plugins.promoted__builds.conditions.GroovyCondition_-Badge>
              <displayLabel>Custom Groovy script condition</displayLabel>
              <variables class="empty-map"/>
            </hudson.plugins.promoted__builds.conditions.GroovyCondition_-Badge>
            <hudson.plugins.promoted__builds.conditions.SelfPromotionBadge/>
          </badges>
          <timestamp>
            <time>1479318413549</time>
            <timezone>Asia/Calcutta</timezone>
          </timestamp>
          <promotion>16</promotion>
          <promotionAttempts>
            <int>15</int>
            <int>16</int>
          </promotionAttempts>
        </hudson.plugins.promoted__builds.Status>
      </statuses>

If i remove this section from xml and restart the jenkin promotion status will be unmarked. But i am exploring a programmatic option to do this meta data change without restarting the jenkins!  Any suggestions/clue ?
