How to set a StageNow port

I have StageNow working from my MC40 Android Kit Kat handheld. However each time I run through the staging process it appears to attempt to pick a random port from 16,000 - 60,000 to connect to the StageNow server. If I open that block of ports on the StageNow server, then the process works fine, but I'd rather not have all of those ports open. Is there a way to limit the port range it uses?

 

Thanks!
