I'm looking to create a project-specific rank field that will be auto-updated if a rank on another ticket changes. This would not be using the Jira global rank feature, but a separate custom numerical field.
For example, if in project A I have the following issues:
A-100, Project Rank = 1
A-200, Project Rank = 2
A-300, Project Rank = 3
If A-100 is closed and I remove the number from the Project Rank field, I'd like to have A-200 move to Project Rank = 1 and A-300 move to Project Rank = 2 automatically.
Any thoughts on how to do this?
