Option to change the date of automatic monthly reporting

Hi, 

Can you please add an option to change the date of the monthly ranking check? 

For example, we want to be able to choose the date 28, 29 or 30 of the month, so we can get the ranking checks of all our projects by the 1st or 2nd of the month. We need that because of our large number of projects, and they will finish all the monthly checks only on the 3rd or 4th day of the month. For us, is too long time, as we need to provide monthly reports to our client, that include your ranking checks, in this time period. 

Thank you in advance
