Mapping multisite to subpath of same domain?

Hi everyone,

I am using currently WordPress domain mapping to map a site in my network to an a new domain (i.e. http://www.example.com). I managed to set that up fine.

I would now like to map another site in the network to the same domain but as a subpath (i.e. http://www.example.com/jp/). I am creating the same site but just in a different language.

I am just making a couple of simple static pages that will appear in different languages.

Could anyone please point me in the right direction?
Many thanks!
