Change resulting objects in change activity to Under review before release

Hello, 

Im looking for a way to lock (change to status Under review) resulting objects during Design review. We have a similar process for Promotion request with following expression : 

wt.maturity.PromotionNotice pn = (wt.maturity.PromotionNotice)primaryBusinessObject;
try
{
wt.maturity.MaturityServerHelper.service.lockTargets (pn);

}
catch( Exception wte )
{
wte.printStackTrace();
}

Is there any way to apply this for Change activity resulting objects? 

Thank you very much in advance.
