Netflow 5.5 EA Reports

I want to schedule a report that will be issued at lunchtime and summarises the morning's activity. Is there a way of doing this?

There seems to be a time filter available but this only appears when the 'Previous 24 hours' option is selected. However, if one sets it it seems to be ignored or does strange things to the data. I just tried two exact same reports, one with the filter and one without and the results were not the same. It is not mentioned anywhere on the help page. What does this parameter do? If I set this value then I can change from 'Previous 24 hours' and it appears to be kept (although you can't then change the time filter). I've obviously misunderstood it.

With the weekly report, would it be possible to add a Monday to Sunday option?
