Adding the id as a prefix of the title of a created elements

Hi there, Keith!

I checked the code again just in case, and the ref value is auto generated in a post save signal (so it is not available before the save). You can either do it after the save, or globally on this method, something like this:

// ...existing code...
def attach_sequence(sender, instance, created, **kwargs):
    if not instance._importing:
        if created or instance.prev_project != instance.project:
            # Create a reference object. This operation should be
            # used in transaction context, otherwise it can
            # create a lot of phantom reference objects.
            refval, _ = make_reference(instance, instance.project)

            # Additionally, attach sequence number to instance as ref
            instance.ref = refval
            
            # Add ref prefix to subject if not already present
            if hasattr(instance, 'subject') and not instance.subject.startswith(f"{refval} "):
                instance.subject = f"{refval} {instance.subject}"
                instance.save(update_fields=['ref', 'subject'])
            else:
                instance.save(update_fields=['ref'])

That would affect all instance types, though: Issue, Task, Epic and User Story. I did a quick try and it seems to work, let me know if that works for you.

Best!
