I'm trying to create an automation that will assign the issue to one of the users from the list using balanced workload or round-robin, and I'm looking to pass the user list from external webhook. But when I'm trying to setup automation I only see the option to "type to find matching users", which don't really works for me. There is an option to assign to a smart value, but from what I understand, it expects to see only 1 user in the said value.
Can something be done to achieve it, or will I have to offload Balancing to external automation services like Tray?
