Is there a way to schedule, launch and distribute a Crystal Report from the Windows command line?

Although I used BI Launchpad for this, I originally submitted this to BI area and it was rejected and I was told to post on Crystal Reports area.

I have 4 different Crystal Reports from which I generate about 110 report instances with varying input parameters, delivery distribution lists and schedules.

I now have updates for the original 4 Crystal Reports and want to update all the scheduled reports with the updates.

Is there a way to change the underlying report, but keep all the scheduling and distribution information associated with these existing 110 reports?

If not, if there's a way to schedule a Crystal Report along with all it's distribution info from the Windows command line, then I could script the invocation of all these reports and it would be much easier to maintain.

Thanks
