[Ideas] BPT: Rollback\Undo Activities

In Service Center Process Management we could have the ability to undo / rollback the activities, one by one or directly to some point in the process.

This would be very usefull in situations where something went wrong and we need to fix the process execution and run it again from start of just from some specific point.
Instead of deleting activity records in the OutSystems database it would be much simpler and safer if it was managed by Service Center itself.
