Saving a Rush MOGRT

Hello, I'm trying to edit a Rush mogrt and then save it as a template for others to import in Rush on their machines. Several years ago, I was able to do this, but now I can't figure out how. I can save an edited graphic as a template, but I can't find a mogrt file with that name, just the Rush Bundled Templates folder in Library/Application Support/Adobe/Common/Motion Graphic Templates.  I can find the mogrt in my Creative Cloud library, but I can't figure out how to successfully share from there. 

Help!
