Help with key-in command to change reference global linestyle scale

What is the correct key-in command to change the reference global linestyle scale? We have a reference with global linestyle scale set to Master, but we want to change this to Reference across multiple sheets. 

The file name in Microstation is PW_WORKDIR:d0136974\X-Topo-CF.dgn. I've tried using REFERENCE SET GLOBALLSSCALE=REFERENCE PW_WORKDIR:d0136974\X-Topo-CF.dgn, but it does not work. Is there something that is incorrect or missing?

Edit: Fixed the issue, I used REFERENCE SET GLOBALLSSCALE=REFERENCE X-Topo-CF.dgn  and it worked fine.
