Worklist item delegation question

Hi,

I have a workflow that requires an approval from 5 approvers, Let's call them Approver A, B, C, D, and E. I have added these approvers within the destination set. 

However, let's say if Approver E is stalling the process and Approver A wants the Approver E's worklist item to be delegated to him, I could not get it to work through the management worklist.  The worklist item does not appear on Approver A's worklist.

I ran a quick test and "delegated" the worklist item to somebody who is outside of the destination set (Let's say, Person Z) and the worklist item shows up properly.

Any thoughts on this, anyone?

Thanks,

 Brian
