I cannot give you a date when this feature will be available, because our priority at the moment is to release GenoPro 2.0. See http://www.genopro.com/beta/#todo for our schedule. Once GenoPro 2.0 has been released, be will create a new schedule based on the most *urgent* needs from our customers.
By the way, GenoPro has built-in copy & paste with other applications such as Word or PowerPoint. As a result, you can always add a background image to PowerPoint before pasting your family tree / genogram in it.
