Data Binding for Multiple Test Cases

Hi, Adding test data in data binding is allowed only for 1 test case at a time and not to multiple test cases in test suite.
My requirement is to select all the test cases in test suite and do the data binding to one test data file.
It is time consuming to click on each test case in a test suite , add data binding , expand the iteration window and modify the iteration, and perform map all.

Is there a simpler way to perform data binding actions for test suite level rather than test case level? Please assist, if any.
