Add a label when an issue is moved to another project

[Gordon Andersen]

I'd like to automatically apply a label (unscreened) to an issue whenever it is moved to another project.

The Move does not seem to follow a workflow and hence does not trigger a transition where I could add a post-function to add the label.

Does anyone know how to solve this?

Automation for Jira Add in could help here.

You can set up an automation on an "Issue Moved" event that can add the label.

You can also use one of the scripting addons to do the same thing (listen for the event and take an action.
