User Options: Preset Date Range or Custom Date Range

Hello everyone,

I have built two reports, one with a Start Date and an End Date, and another with preset ranges (Last 7 Days, Last 30 Days).  I am trying to see if there is a way to have a single combined report with maybe the following three fields:

1. Date Options - Last 7 Days, Last 30 Days, Custom

2. Start Date - Auto-fill if Last 7 or Last 30 selected;  Leave-alone if Custom

3. End Date - Auto-fill if Last 7 or Last 30 selected;  Leave-alone if Custom

Can anyone help me consolidate the report, please?

Thanks in advance.
