How do I change the port in debug mode in Eclipse?

I am trying to debug a node.js project in Eclipse, running the code locally. I choose "debug as node.js project", but I cannot seem to change the port from the default. In other words I want to run this:

node --debug-brk=3000 C:\Users\denman\workspaceNonAndroid\XXXNodeXXX\app.js 

instead of this:

node --debug-brk=5858 C:\Users\denman\workspaceNonAndroid\XXXNodeXXX\app.js 

on a related note - can I run those commands from the command line and see a debugging session in Eclipse, perhaps? How do I run those commands from within Eclipse?
