Question Multiword - Customized world setting?

So I've looked around and haven't found anything that helps. I'm trying to get multiword to accept a custom generator (the vanilla custom generator).

The way you would do it on a vanilla server would be:

generator-settings={...}
...
level-type=CUSTOMIZED
...

The problem is that that goes into the server properties file, but I need it to work with multiwords. Does anyone know if thats possible to do?

Thanks,
