I'm not sure what you mean by "autmatically" but maybe this could help...
In the admin interface go to the "My account" tab, and there on the ledt under "Edit mode settings" set "Location" to "on". After that when you go to create a new object, in the edit window wor that object you will have a "Locations" section on the bottom when you can add locations to the newly created object.
Another way to add locations to the object is to go to it's full view after publishing it and add locations from the "Locations" section in the full view. In order to see the "Locations" section you have to have the "Locations" button on (it's a the thin button on top of the objects view).
I hope this helps a bit. Is this what you wanted or something else?

Nothing is impossible. Not if you can imagine it!
I know you can add locations, and that is how I was going to do it manually. However what I want to do is with this content type there are a few options, so when adding content I would like a user to be presented with the folder options as checkboxes.
