Do you have a sample workbook by chance?
Does that sample data need to come from the same date as the 'real' data? If not, you could create a calculation that looks at a parameter to choose which data to show and have the parameter be the filter. For example, if the filter needs to be 'Color', you could have the default parameter value be 'Choose Color' then have a calculation that says:
If([Color]="Choose Color") then [Sample_Data].[Colors] Else [Live_Data].[Colors] end
