DataStacks are a method of combining DataSets to perform various calculations. DataStacks, once created, are a DataSet. Thus, DataStacks use most of the same properties as a DataSet, except for the Statistics tab, which has only some of the options available.
Setting the DataStack Values section of the DataStack Properties dialog will allow you to override any individual DataSet Spec Limits to use a single spec limit to the entire DataStack.

Once you have selected how you want to synchronize your DataSets, select DataSets... to select which DataSets you want to stack.
