Sometimes a workflow may not complete to run due to a number of reasons.

Instead of 'Re-running' the complete workflow from selecting a file it will be ideal to allow the option to 'RE-ASSUME' the workflow from where it failed/stopped.

The most important benefit is avoiding to use additional time to re-run again part of the process that was previously successful, and instead be able to continue the workflow from the point where it failed (e.g. avoid the need to select the input file again).
