Use a calculated report as base for multiple reports with additional filters

SOLVED

I have a customer that updates up to 2500 invoices in a day.

I have created a report that pulls all the necessary header and line detail information to produce several pivot reports.

Is there a way to now use this report (so it does not have to be recalculated) to produce 25-30 further filtered reports.

Those 25-30 reports will be individually emailed to management personnel and sales reps in the field.

If this is documented somewhere, please point me to the documentation.

As always, thanks in advance for your assistance.
