Send selected item forward or backward in layer order with Pages for iOS

I have multiple drawings in a Pages document that overlap. Using Pages for iOS I would like to change the z order of the layers. For example, with some items selected I would like to be able to “send backwards”, “send to back”, “send forward” or “send to front.” For small selections it is possible to bring an item to the front using cut and paste, but this doesn’t scale well when there are more than just a few items. Is there a way to do this? Thanks!
