Date property in reports : add next days

Hello! 

 

I am working on reports and would like to see how many contracts will begin in the next 7 days, 14 days or 30 days. I have clients starting contracts on stamp dates. 

For now, it's only possible to have the last 7 or 14 days (see picture). Would it be possible to add it ?

Thank you for your help!
