ROSLYN SCRIPT AND GLOBAL VARIABLES

I am using Syntax Editor to edit Rosyln Scripts. Everything works great. Intellisense and code completion work. The only issue I have is that the editor does not know about the global variables introduced when the script is evaluated. Research has yielded that there is a HostObjectType parameter on ProjectInfo.Create method. Do you have a way to set that value so the editor will see the global variables?
As always tanks for your help.
