Hi. What I'd like to do is this below.
- set a number in Original Estimate in Sub-Task
- set the same number in a custom_field inside its Parent ticket automatically.
The Original Estimate is the one used with Time Tracking.
I'm trying to achive this by using Jira Automation but Original Estimate cannot be chosen in the option in the "Field Value Changed" action.
Is there any way to choose Original Estimate?
Or if it's not possbile to choose, is there any other way to achieve this above?
