Modifying settings without the Eclipse Plugin

Hi folks, I'm new at developing for Connect IQ (used to develop apps for the Pebble) :)

I've just developed a watchface with settings - here's a preview - http://imgur.com/a/XZDmR

Now I'm looking to test out the settings before I publish on the App Store.
After looking in the forum, I can see that one way to do this is via the "Eclipse Plugin".

However, as I'm working purely on the command line, I have not such option.
Is there anyway to change the settings at runtime within the Simulator?

Cheers.
