Workflow design: how to return to previous workflow step

Question

Hi all, I have the following requirement in a workflow with about 10 states: 
 - It shall be possible to put the workflow execution on hold and continue it on a specific date. Putting the workflow on hold shall be possible from each of the 10 states. Once a given date is reached, the workflow shall continue it's execution at the state where the user decided to put it on hold.

Now my question: I think the most simple solution would be to have a state "on hold" and once the target date is reached, the workflow would automatically return to the previous state (see workflow picture below). However, I am not sure how I can return to the previous state. Does anybody have an idea how this could be done?? E.g. if the user changed the state from A to "on hold", then the workflow should automatically return to state A once the target date is reached.

Thanks for any inputs. 
 Best regards, Beat

Well the manual way is when object enters State A, B, C you set the Previous state to that state with set property, and when the object goes on hold, you leave the previous state at it is, so that you know where to send the object from On hold State. 
 If you have a lots of states, it is difficult to manage that. 
 With Managed Properties, it might be doable, but now I am holiday and can&rsquo;t be sure until I check. 
 With VBscript it is for sure doable without the property. You would need to search for previous version of the object to check what was the previous state and transition the object to that state.

Hello, 
 You can add a Property Definition where you add what was the previous state, and add the transitions based on that property.
