Multi-tenancy

Is it possible to run self-hosted InvoiceNinja in multi-tenancy mode? Is this the same as having multiple companies?

Ideally I would like to have company1.mysite.com and company2.mysite.com to be two separate instances of invoiceninja but sharing the same laravel codebase so that I dont have to maintain separate installs?

I found this config option - ALLOW_NEW_ACCOUNTS=true but am not sure if that is for multi-tenancy / multisite?

Our applications supports multi tenancy (we use it on invoiceninja.com) however we only provide support in this area to our resellers.
