How to tell openshift to do npm install to update a package and restart the app?

I have a node.js app on openshift and a package that it uses which I update frequently. So I also put "mypackage":"latest" in the packages.json for that reason.

I want to tell openshift to update that package and restart the app.

rhc app restart just restarts the app without doing npm install

Is there any way to do that?

_{(Other than unnecessarily updating app's code and pushing the changes, which is plan B)}
