Online Invoice: Ability to select the unpaid invoice statement which day of month to send out

I agree ... The ability to change the date when the unpaid invoice report is sent out would be helpful.  End of Jan falls on a Friday so the unpaid invoice report will be sent on Monday before i have a chance to send the statements which confuses our customers so i will have to turn it off.  Also is there any way of just sending an unpaid overdue invoices list to customers as i have customers ringing thinking that all of the unpaid invoices are overdue but they are not .. some could be overdue and some for the current month not due yet.
