@crawn23,Thanks for posting in Q&A.
From your description, I know that you want to know if it is possible to auto update win32 apps using supersedence.
Based on my research, I found that you can create one or more supersedence relationships between apps where you update or replace somethings. And whether it can auto update win32 app is depending on how you assign the supersedence app, if you assign it to required, it will automatically update win32 app, if you assign it to available for enrolled devices, the newer version will appear on Company portal, and you can install it.
