Use Categories Spreadsheet to present the values for the user. Unify User creations form.

The objects are always created, so it is not required to
check if transition is possible.

Move configurator after script from Business Template to Workflow. This will make management easier

Instead get Informations from the Business Configuration, get information directly from the Workflow Document. This easly creates a identity if the workflow and also simplify the process of Pré-configuration.
