Pass parameters from loadUI to soapUI from the command line

Hello,
I'm just starting with loadUI and am hoping to use it for automated testing.
I searched the loadui.org site and the forums and didn't see any answers for what I'm looking to do.

I have some soapUI tests already written, that I'd like to use in loadUI. I have my test set up to use the soapUI runner.
When running the soapUI test directly from the command line, I can specify the host (endpoint) IP. If I run loadUI from the command line, is there a way to pass the endpoint IP as a parameter so that it will be passed though to soapUI when the soapUI runner is started?

Hopefully that question makes sense. If not, let me know what else I can provide to help figure this out.

Thanks,
Josh
