Use specific Jibri instances for Subdomains

Does anyone know if its possible and if so how to, enable specific Jibri instances to be called from a particular sub-domain? Ie if I have https://meet.jit.si/AccountOne/Meeting1 and https://meet.jit.si/AccountTwo/Meeting1, can I have the AccountOne meetings use one batch of Jibri’s and AccountTwo use another? I am using a self hosted instance but would prefer to only modify source if absolutely necessary and I feel as though this may have already been solved and I am just not finding it.
