I think Digilent provides these presets in an XML file. When I compared the .xml file for my board to a .tcl file for another zynq board they look like the same properties in a different format. I think you can manually import them using the Import XMS settings button to the right of the Presets button. I imagine the comments above also apply in that these preset will automatically get applied if you use the Digilent supplied board file.
