Does Zendesk support multiple JWT SSO integrations?

We have a ServiceNow Scoped application, which is installed by clients on their ServiceNow instance.

Is it possible for us to configure multiple JWT SSO integrations (one [or more. if they want to test] per customer)?  

I have read this link on Multibrand - but I believe this is a slightly different scenario - in our case (I believe) this would require different credentials, one for each client install.

Thanks
