When using a Parameter to specify a member in a CubeView, how to specify Workspace the Param is in?

That's a very good question... summoning ckattookaran ,  ChrisLoran and NicolasArgente , they like to play with latest releases more than I do...

One hypothesis floating around here is that when a Named Workspace used to launch a non workspace contained item, a CubeView in this discussion, the parameters of that item will be looked up in the Named Workspace presenting the item first and if not found, in the default workspace. 

If this is the case, it would make for some interesting flexibility in that a single parameterized CubeView could serve a different purpose for each named workspace that presents it.

I haven't had time to test the idea yet.
