How to set the assignee to the current user if issue is unassigned?

With post functions you can set the assignee of a issue to the current user within a transition. The post function: "assign to current user" almost does what I need but it overrides the assignee.

Is it possible to only assign the current user if the issue is unassigned?
I don't want the values to be overridden.

The jira server is running jira 8.6

Hi @Quin Ligteringen

You will have to purchase a 3rd party plugin like jmwe that had conditions. Or jira use automation.
