Scheduling Summary Report for specific time window

Hi.

I want to schedule a daily summary report for a specific time window of each day, Is it possible?

I managed to create a duplicate summary report and arrange the displayed info the way I want, but I don't want the report to be for the whole previous day, I want it to be just for working hours, 8 AM to 6 PM in this case, everyday. I can do it manually, but I want to schedule it to run everyday reporting the previous day's working hours.

Any help is appreciated.

Thanks.
