Copy project key all the way to subtask summary

[Ahbosch]

I want to copy the main project key example "AB-1" to a Task Summary to begin with AB-1 - summary, (Which I can do via automation), but then from that Task create a sub-task and again copy the AB-1 into the summary.

This way I can easily see what sub-tasks belong to each project.

This is my current automation call for the Project key:
{{issue.parent.key}} - {{issue.summary}}

I'm also trying to find a way to copy a custom field into the summary, but I haven't found a way yet. 

Any help on this would be appreciated.

Using Create Issue Trigger you can check for parent summary and copy it.

Can you share the screen shot of your automation to understand the flow better?

Thank you for taking the time to assist me with this. 

This is what it's creating:

here is the automation:

What I would like to see is to have CP-236 to display "CP-1 - W2401 -{{issue.summary}}"
And the same for the sub-task:
Instead of getting the key from the task to get it from the project, have CP-237 display "CP-1 - W2401 -{{issue.summary}}"

When you need to update subtask summary, use

{{triggerIssue.parent.parent.key}} - {{triggerIssue.summary}}

When you need to update standard issue summary, use

{{triggerIssue.parent.key}} - {{triggerIssue.summary}}

See sample automation that i created for your understanding. I used manual trigger, you can have the trigger based on your use case, like Create Issue etc...
