I actually had a co-worker do the same thing. he used an HTML Snippet on the page and set it for javascript with jquery. Then added the following code within the control. This code will find the alert.danger css class that is visible and is tied to the css selector widget we use for error handling on our controls. Then it looks inside the modal-body.mx-window-body (wrapper of the page) and scrolls to the first error is sees. The bottom two numbers determine how quickly the screen scrolls to the control on the page. Hopefullyl this helps.
setTimeout(function() { var firstError = $(".alert-danger:visible").first();
$('.modal-body.mx-window-body').animate({ scrollTop: firstError.offset().top-350 }, 200); },250);
