Yes, absolutely. If you want to add an identical button to one you’ve created (same display time, size and font size) simply click ‘Save and Add Another’ and the next button will inherit those configurations. You can change the button text and click action and move the new button around on the screen to create the display you want.

Conversely, if you have buttons that you’ve configured independently but have overlapping display times, they will display at the same time for the period that they overlap.
