PWA with dynamic url

[MichelJonkman]

Is it possible to use PWABuilder to create an app with a dynamic url? With that I mean that users will download the app and can then choose what url they want to use.

I'm building a platform where every client gets their own domain but if I add the app to the app store I don't want to have a different app for every client, just a single one where they can choose their own domain. I could of course do this using a proxy of some kind but it'd be nice if it could be built into the app itself.

It would be acceptable if it only works for subdomains!
