Hi Peter, Thanks for the reply. Does anyone know how to execute a specific workflow from the command prompt? E.g. run the workflow as a job? Then I could perhaps write a workflow wrapper tool to overcome this shortcoming.

You can for instance start a new history, run workflow #1 with N tool steps, then workflow #2 with M tool steps, and save this history as a new workflow #3 with N+M tool steps. This has the downside that if either workflow #1 or #2 is changed, this does not alter #3 - which is an independent copy. Peter
