Grouping Desktop Stacks by file extension?

[kipwheeler]

Is it possible to group your desktop stacks by file extension?

I see "Kind" an "Date" and "Tag," but something that let me stack them by .png and .docx and .pdf would be way more useful. When I stack them by "kind," I end up with all the .png and .docx and .pdf in one lump. Is that the way it is supposed to work?

What is the name of that lump?

Update: The lump was merely labeled "Other."

Note that I flick on "Other," when the stack expands, it shows me the materials lumped by image type. It just all reverts to a single stack rather than one stack for screenshots, one stack for documents, etc, which I'd greatly prefer.
