Schedule Report to run last day of month.

I need to run a report after close of business on the last day of every month. eg. at 9pm. How do I set up a schedule to do it?

can I set a workflow to run a report?

Can I add a new entry in the schedule dropdown list

Or create a formula that will trigger it to run?

There is an enhancement request for this feature going back to 2011, so I guess the powers that be don't think it's worth doing.
