Test Studio supports data driven find expressions:

However this is not pushed into the auto-generated Pages class. As a result coded steps don't get the added advantage of data driven find expressions. You can hand code them, but this is a loss of efficiency, especially if it has to be done twice or modified. You now have to modify the data driven portion in two places: 1) Elements Explorer 2) one or more coded steps.
