Hi @mrzane42 ,
As it would turn out, it looks like we can support this right now! Our application is Electron based, which uses the Chromium browser. It turns out the Chromium browser already has features to override the user data directory via command line argument.
If you launch Logic.exe with the option --user-data-dir=<path> it will store all of the application configuration files there. (including config.json)
I’ve tested this like so:
"\Program Files\Logic\Logic.exe" --user-data-dir="C:\Users\markg\Desktop\test"
