Tree view for managing device dependancies

I'm trying to configure my device dependencies, but the Quick Configuration wizard only lets me add or remove individual devices or entire device groups. The problem is that don't see a way to quickly set up multiple devices that don't belong in groups, and I can't see a "birds eye" view of the entire tree structure.

What about a Map option for an overview of all device dependencies? Like a tree-style view where we can see the "root" devices (like core switches), and be able to expand (or drop down) the devices that depend on it, and so on?

The map view would be good to see the dependencies, but that doesn't solve the configuration part... I propose adding a "drag and drop" functionality. It would make it very easy to configure the dependencies to simply drag a device into the correct location.
