This one might be a tad tricky with just SPD, but my hands are tied in terms of what I can/cannot use.
I've got to go and add the ability for a supervisor to go in on a workflow and say "These groups in this order" need to approve and comment on an item, and then assign a task to each of those people. As well, I need it to not continue on the workflow to the next group until each of those tasks is approved, but I need the ability to have the supervisor be able to move an item through a state.
A solution is to use a state machine workflow, but that requires the supervisor to manually move the item between stages, and they want it automated. So i need a sort of hybridized state machine & automatic workflow.
* Must use Sharepoint Designer to create the workflow.
* Must not use any external functionality (InfoPath, Customized Code, Visio, etc.) to create the workflow.
Is this even possible? So far I have not been able to find a solution for this, even on the TechNet forums.
