Multi-domain-multi-webroot usage

I have a copyparty server at `copy.examp.le`, and I have a share on it called `vol`. I would like this share to go to `vol.examp.le`. Is this possible at all?

I got about as far as to make the `vol.examp.le` go to `copy.examp.le/vol`, but this obviously breaks the whole UI.

I also saw `rp-loc`, but this is for the whole server so wouldn't work here.

Thanks - sophie.
