Change app title dynamically in UWP

Question

I'm currently building an app that starts recording the screen at some point using Windows Game DVR. That recorder takes the app name as file name when it's done recording.
I found out how to change the app title using Applicationview.GetForCurrentView(); and it does change the title of the window of my app. However, it doesn't take this title into the filename after recording.
When I record something like a Word document or my Visual Studio Project, it does show the specific name in the filename, so there must be another level where the name needs to be changed.
Anyone has an idea?

Based on this thread you cannot do that.

It seems that Xbox DVR gets the name of the installed app and that cannot be changed at runtime. For changing the app title you need to first uninstall the app, modify Package.appxmanifest and then install the app.

What about a little workaround here. You know your app name when it is installed and you know where Xbox DVR saves video file recordings. You can write a file system watcher that will sense new files in that directory and rename those to your needs.
