Print a monthly report from a timesheet. How?

Hi all,

How can I print a montly report from entries in different timesheets.
Per project I enter timesheet info for everytime I worked on that project.
These working times can span multiple months.
Now I want to create or print a monthly report.
Say I have two time-entries in my timesheets for July, and 8 for August. I only want to print (or set a filter?) the entries from August.

I think I have to filter these timesheet entries by Projectname (I work on multiple projects) and month to get the result I want. But I cannot find anything that can help me get this accomplished.

I use timesheets almost the same way as in the demo database Timesheet form Ninox.

Any help would be appreciated.
