In Tableau 22.4, you can now swap a data source for a single sheet making it easier to test out new data sources, try out alternative calculations or even use both data sources to achieve complex analytical calculations.

Tableau Release Notes:
Selectively replace data sources on a worksheet level without complicated workarounds. Previously, replacing data sources would apply to all worksheets in the workbook using the datasource. Now, you have greater control and can select to apply data source changes to only the current worksheet.
