TI Import Control File Help

I currently use Dynamics SL 2015 and I am trying to update some fields in Inventory Items using TI import.  The control file I have changes cclassid and cGLClassid.  However, our system has a system message pop up when these two fields are changed with a "Yes" or "No" button to press.  How do I tell my control file to press the "Yes" button on a pop up system message?

Thanks!
