Hello there!
In the last years, one specific issue has been brought up quite a few times, but Atlassian has failed to recognize a certain use case.
We are a mid size software development agency, and we give our customers access to our Jira and Confluence instances. To prevent colleagues to communicate with a customer in an inappropriate way, we added "(COMPANY)" to the full name, when we were still using Jira Server, so e. g. "Gabe Newell (STEAM)". This was a convenient way to make it very apparent that this particular user is in fact a customer.
Now in the Cloud environment, the Atlassian accounts belong to the users themselves, which is fair. But we need a way to accomplish this.
There is ID-6415, which has a lengthy explanation of what can be done, but it misses one of the main use cases: What if the customer has their own Atlassian Cloud organisation, because they are running their own Jira, or they are already participating in different Cloud Jiras? In this case it's not possible to ask them to add (COMPANY) to their name, nor is it possible to ask them to let us manage their email domain within the Atlassian Cloud system.
It has to be acknowledged that the world needs something like "Local Nicknames", which would enable Site or Organisation admins to (locally) rename users that participate in the collaboration, but are not managed by the Organisation.
Many other services have this feature, for example Discord, which has "Server Nicknames". It shouldn't be rocket science to implement.
Thanks,
Ingmar
