FHIR Chat · Filename override

I'm generating NamingSystems and they end up in the examples folder (because they are instances). I want them in the vocabulary folder
Can we have a
* filename = override when declaring a resource?
suggestion for syntax:
filename = is a path / filename related to sushi's output folder (which is may be the igroot\input folder, but that is another discussion)
filename = myFolder/my-resource-id creates the myresourceid.json in the myFolder folder
filename = myFolder/* or filename = myFolder/ uses the folder foldername but gets the filename from the resource id - and creates the file called {resource-id} in the myFolder folder
