Question on workflow administration

[BELLINI, TONINO]

Hello
 
I have the following requirement to cover using SAP workflow. Can anybody give me any suggestion?
 
1. At the end of the work shift all the WF items of an agent must be directed in the manager's inbox
2. The manager should be able to redirect them to other agents on a percentage basis (for example  20% to agent a, 30% to agent b, 50% to agent c).
 
Thanks and regards
 
Tony
