The only way to change the selected dates for a report is to go into Edit mode.  This can be quite dangerous as brokers may accidentally delete certain items from the report without realising, and there is no backup.

If there could perhaps be a dropdown box of months next to each report the user can select the relevant month without going into the edit screen.  This is mainly for the bordereaux and statements which get run every month on every system.  We have already had the conditions deleted from a report so it does not bode well for the future.
