Hacky workaround:
Bind the path property with a property binding on any property (you actually need access to the transform part of the binding).
Add a transform to the binding.
Supply the following script: return "/".join(self.view.id.split("/")[:-1]) + "/desiredViewName" where “desiredViewName” is the name of the View you want a relative position of.
In this example, I bound against view.props.loading.mode, but I don’t need that value - I just need the transform. Note the returned value in the binding dialog preview area.
With that binding in place, I was able to drag my something directory around into different locations of my View directories and the references to other Views within the directory remained functional.
