Sickness Queries to include Long Term Sick Cases without having to run a separate query

Currently, if you run a report on sickness in the previous month, it will not include the long term cases that have not commenced in the previous month but are still ongoing during that month.

The only workaround is to complete separate queries for each long term sick case.

It would be hugely beneficial for sickness reporting to include a filtering system that includes all cases of sickness in a given month.
