Delete a slot dynamically.

Hi,

is it possible to add/remove a slot dynamically using Management API. The closest I have tried is

workflowServer.CreateActionInstanceRight(oActInstRight);

workflowServer.DeleteActionInstanceRights(arTmpActInstRights);

However this just removes the worklist item but not the slot. I have a outcome rule "All Slots = Approved".

Is there a way to achieve this?

Thanks.
