This is mainly for the BIM Manager / Template Development functionality;
The ability to make a schedule list of all the schedules in the project file. This would allow for quick exporting of the list of schedules for Template Development & Creation / Template QA. Having the schedule of schedules would also allow us to make parameter changes to the schedules now offered in the Revit 2018 (and forward) release where we can organize the Schedules similar to the Views. Allows for more control of the BIM Manager and quick changes as requested by the design teams.
