Multi-tenant Kibana 3

I am trying to set up a multi tenant instance of kibana 3 on the same server using httpd. I am basically installing kibana into separate directories for each tenant and defining a different kibana index for each. This works except for setting the home dashboard sets it for all tenants rather than the tenant I am on. Anyone know where home gets set?

That's set in the config - default_route : '/dashboard/file/default.json',.
