You may’t have objects on the slide format all the time be on high, however you may carry out regular layering operations comparable to ‘Carry to Entrance’ work with slide format objects by enabling ‘Permit layering’:
If you’d like slides based mostly on this format to permit objects to be layered beneath slide format objects, click on the background of the slide (in order that nothing is chosen), then choose “Permit layering” within the Format sidebar.
