I have a multi-select called Goals. In that, there are several goal options. I am wanting to monitor that field and if a new goal is selected, it automatically creates a child issue type for that particular goal. Each goal in that multi-select is a specific issue type for me. However, the automation is not just looking at the newly added goal and creating the issue for that, its creating an issue (duplicate) for the other goals that were already selected prior to me selecting a new one. So I'm ending up with a lot of duplicate child issue goals. How can I get it to just look at the newly created one?
Here is what I am doing now. I have a branch for each goal type.
