My company as well has two Jira instances that need to be linked to our singular Zendesk instance. 
Each instance of Jira needs the ability to be integrated with Zendesk. 
We have no issue creating service accounts as admins in Zendesk to facilitate multiple integrations, but this 1:1 limitation prevents us from connecting our second Jira instance to our Zendesk environment. 

We are a SaaS company and one Jira instance is Engineering/Product tickets where bugs and feature requests are logged/worked. These are generated from internal employees and Zendesk support tickets reporting bugs or asking for new features. 

The second instance is IT, Ops, Customer Success, so anything done to the customer's environment is logged here and needs to be attached to support tickets within Zendesk as well. 

Thank you.
