Using RandStream objects in mask initialization code

Is it possible to use a RandStream object in mask initialization code? For example, in the mask initialization, I'd like to be able to write:

x = rand(mystream,2);

where 'mystream' is a RandStream object. But since the mask initialization code runs in the mask workspace, how can the stream get there? Can streams be sent into the mask as dialog parameters? Is the only option to create mystream in the base workspace and use something like evalin in the mask initialzation code to get to it? Or maybe load mystream in from a file? Other options? What if the mask resides inside a referenced model? Does that matter?

I just tried this, and it looks like you should be able to pass in a RandStream object as a mask (dialog) parameter. Does that not work for you?

It might work in some cases. I was thinking about possibly passing a RandStream object into a referenced model via Model arguments and using it to randomly initialize a parameter in a masked subsystem in the mask initialization code. Don't know if this is even feasible, but I stopped investigating once I learned that mask initializations and model arguments don't play nice together.
