it’s possible to have 1 or some  customer in more 1  company ?

I try to explain. I have 10 agencies and each customer have their company ID (IT Paris, IT Lille, IT Luxembourg, ….)

So each customer in Paris see all ticket for our company, that work fine.

But my boss when he log on the customer interface want to see all ticket for group company (Paris, Lille Luxembourg,….) actually he just see the ticket of Paris .

It’s possible?

And if it yes how I can do that
