Alert Scrolling

When sending an alert to the audience (for example to inform the kids that they are going to go out to their groups) I would like an option for this to scroll across the screen, is this going to be added in a future version, if you do could you add an option to show alert for a length of time (or a number of time it scrolls past the screen). Easy Worship has this function and I would like to see it on Worship Tools Presenter.
