I work for a big structure that has an altered WebApp Builder Developer Edition* as a application generator. I have to work on this version and develop some custom themes and widgets. Everything works fine apart the propagation of my last versions to the existing generated applications. When I deploy into client/stemapp it won't affect the server/apps/* unless I open each one of them then I proceed to some manual operations.
I know a way to do it would be to deploy my files in each app (while there is not a change in the structure of the config.json files) but I was wondering if there was some existing tool to do so. I acknowledged this article (https://developers.arcgis.com/web-appbuilder/guide/upgrade-apps.htm) but it doesn't seem to be adapted to my case because I only change few things in my themes/widgets so it is not relevant to get separated installations.
* In fact, it's arcOpole Builder, an altered branch dedicated to the french issues and developed by ESRI France
