DataSets come in two parts, the DataSet itself where you define the structure and record the data, and the DataSet View where you configure how your data will be presented on a Display. Changes can be made to the data in the underlying DataSet which will automatically update the DataSet view with the new data.
Please do take a look at our Manual for further information:

Another suggestion would be to create 2 different schedules on 2 display groups. You could then switch the membership of the displays between the 2 groups to follow an alternate schedule?
