No, I don't think it can be done by code. That's why I asked here, and since jcl did not reply with "use code to load the right wrs files depending on whether you run as server or client" I assume it's not possible. Also, the manual's pretty clear on this:
At engine start, all WRS resources found in the work folder are automatically opened, and the files in them become available to the project.
That's usually very good, but in my case makes things difficult.
