User-exit IWO10020/IWO10021 allow for cutomer defined task list selections ( an new menu option appears in Extras->Task List Selection).
So, in theory it would be possible to misuse these exits to call an OCI catalog and return a list of operations to the Operations tab.
I've never seen this done, so I'm not sure even if it is technically possible.
I've also seen one customer "hack" a PM order to show the Service Product sub-screen on the order header tab (as per a CS order). Then use this functionality to display a task list from which the user selected specific operations as required.
