Course Builder

How do you update an app from course builder? In the asset library it says what version an app is but when I republish an app it just creates a new asset. I want to be able to re-publish an app which will then update the original version without me having to create a new card and add it to the page it belongs on. This is a big issue for me right now as I am trying to go back and add Google Analytic Tracking IDs to all of my training apps but that would require me to republish everything, create new apps, then move them too all the respective pages and then re arrange them so they are in order within their collection.
