Further testing of RD shows that it does not support a UNC path structure with spaces.

A typical UNC might be something like this:

\\Computer\c$\Documents and Setting\JohnDoe

There does not appear to be a valid method to DYNAMICALLY reduce or use UNC with spaces in the path.
 
Would like to request RD be updated to support UNC mechanism with spaces in the UNC path somehow, or some method to DYNAMICALLY properly shorten the path for use.
