WorkUnit Metrics Task - Update Status field

Hi There. I would like to know how to make the current WorkUnit Metrics Task rcd inactive or a status of 2 -action taken. We move in basket rcds from task to task at times, even though it hasn't gone thru a User Action Node. We are on LSF9 Rel and I use WeRuns extensively...I have resorted to adding a new task and deleting the previous task rcd.. I would prefer to do exactly what ProcessFlow does, as it goes to another UserAction Node...It changes the previous status to a '2' and adds the next task rcd....This is what I want to be able to accomplish...This way I have a history or trail of a workunit as it went from task to task...If there are other forms that need to be updated to allow the previous task rcd's status to be changed, please let me know all about it...   Thank You...
