The App already has the ability to do what you are asking, if I understand you correctly.
Steps from the Home screen of the App are:
Tap Pencil Icon (Upper Right corner)/Edit Devices (from popup at bottom of screen).
Then Press and hold the double bars on the right of the Device or Group you want to move. Then slide the item up or down until it is where you want it to appear on your Home screen. When you have things where you want them, tap Done in the upper right corner of the screen.
