I need dealerships to have visibility to their customer's issues

[Jack Howard]

Currently, the only people who can see submitted issues are the service desk customers who submit them, and the Jira SM agents who answer them. I need a more tiered structure to share visibility of issues with more people than just those who submitted the issues. 

We tried to use the 'Organization' function within the Jira SM Customers area, to add multiple people to an organization, so that they had shared visibility to each other's issues. This works for customers alone, if they have multiple people within the same customer business who need to see all issues for their business. It does not work if you want to add a regional manager to that visibility, because it shares visibility both ways of all issues ever submitted by the regional manager too. 

My problem with this, is that our international dealer network are there to support multiple customers and I cannot seem to find a way of giving a tiered structure of issue visibility as such:

HQ - full visibility of all issues

Regional HQs - visibility of issues in their region (multiple dealer territories)

Dealers - visibility of multiple customer's issues within their territory

Customer - sees only their business' issues

Any help would be greatly appreciated
