I found a third party app to do this, but it would be best if you could have it built into the workspace.
The app I found is Nimi Places, it's like a fences type thing, where you have a box with a specified folder linked to it.
You should add a function to the workspace where you can add some kind of place boxes, fences, or something, where you can have folders linked to them. And if someone doesn't want any, they just don't have to make them, but I guarantee you majority of people would love this function. I've seen plenty of forum posts of people asking for something where they can view their desktop icons.
