Creating trait with Style Manager property UI

I have a component using the background-url Style Manager property:

editor.DomComponents.addType('mj-hero', {
    model: {
	defaults: {
            // ...
	    stylable: ['background-url'],
	},
    },
});

I would like to reuse this UI that is shown in the Style Manager for a background URL trait that shows up under "Settings":

Is it possible to make a Style Manager property behave like a trait and show up in the "Settings" section, or would I have to create a new trait with this UI?

Thanks.
