Put an invisible function button on top of the button that does your task.
Create your normal task button.
Next, create a Function (screen change) button. Uncheck "Use Shape". This will make the button invisible. Size it the same as your task button, and place it on top of it. It will be transparent.
When the user touches the task button, both buttons will be executed.
