Improvement suggestion for folder hierarchy in File Backup

I've been looking at the dialog for setting up a File Backup, and the "Source" list is very odd in how the hierarchy is presented.

Examples of some problems with the current display of the hierarchy:
a) Everything on the computer is underneath Desktop, which is not correct.
b) Desktop has no checkbox to select all the contents of the actual desktop folder.

d) Items that shouldn't have a checkbox do have one (example: a checkbox next to the top-level Homegroup item -- this should be a dropdown).

I suggest presenting a folder structure more in line with what is shown in Windows Explorer, and more in line with how folders are actually logically structured. Below is what I propose for the high-level items in the hierachy, and a couple of example items in each case:
