Warcraft III new installer

So with the new installer for wc3 you need to install overwatch via lutris and then can run the installer from the created prefix. So inside the overwatch I got directory wc3 as well. Is there any way to ‘mirror’ the prefix to have another entry for wc3 in lutris as well? Thanks!

I have one prefix for all things bnet.

I tried to manually add wc3 and just copied the settings of overwatch but it fails to start wc3 then. Can you share how you accomplished that?
