Is it possible to modify the contents of qpkg.cfg without rebuilding the app?

[sepsol]

I want to change where the app is accessible in my QNAP's web interface. Specifically, I want to modify the QPKG_WEBUI and QPKG_WEB_PORT variables so that I can reuse the same SSL certificate I have on my main web UI for Jellyfin as well.

Currently I can't go to https://mydomain.local:8096 because it gives a ERR_SSL_PROTOCOL_ERROR error since the port/process is different from what was specified on my QNAP's certificate (which referred to 443/https by default). I have to disable https and use http://mydomain.local:8096 only for this app.

I was wondering whether it is possible to change variables I mentioned at the beginning so that I can use the app on https://mydomain.local/jellyfin or https://mydomain.local/media or something similar. I know this would fix the issue because QuMagie runs on https://mydomain.local/qumagie and it works fine.

Thanks in advance for the help and the great app!
