Providing a monthly care planning due report

We would like to have a monthly care planning needed chart rather than weekly. So that reviews can be planned in for the month ahead of time, without items showing as overdue. At present I think we are only able to see what is due in the next 7 days, so if the review isn't able to be scheduled and completed in the 7 days for various reasons it is then showing as overdue - which isn't great for reporting/inspection. If we could have more notice this would enable us to plan workflow, thank you
