I would second this.

Another Method can be set custom property on 'top' level ,or if using script.skinshortcuts, by abuse container.folderpath
which comes with the assumption that you navigate on top level before entering a specific source

-

xml:
<onfocus condition="string.contains(container.folderpath,sources)">SetProperty(CurrentSource,$INFO[container.folderpath],home)</onfocus>

A second method i would think about is

xml:
String.EndsWith(Listitem.folderpath,/) | [!String.IsEmpty(Listitem.FileExtension) + String.EndsWith(Listitem.folderpath, .Listitem.FileExtension)]

"metoo"
