Is it possible to perform Boolean operations on node sets directly in the input file?

For example, I have two node sets: SET-1 and SET-2, where SET-1 is a subset of SET-2. I would like to create a new node set, SET-3, that represents the difference between SET-2 and SET-1 (SET-3 = SET-2 - SET-1).

Other than manually identifying duplicate nodes in both sets and defining a new SET-3, can this be done automatically?

Note: Using Abaqus/CAE is unfortunately not an optionSIMULIAAbaqus
