Combining two reports

Combining two reports

I am a Microsoft Access Developer new to Zoho Analytics. I ran into an issue where filter two sets of dates cancel out one of the other. For example, I have client Start Date column and a client discharge date column. When I filter the start date and discharge date by the same year, both date columns are rendered null. I could write an SQL query, but I was hoping that my non-technical users could manipulate reports with User Filters. If I create a report with only Start Dates and then another with Discharge Dates, is it possible to aggregate both to create one report where both Start Date and Discharge Date columns can be filtered by the same year?
