If component chosen upon initial recording, let the record saver seen as the leader of the component not the one who recorded. How can I do that?
The question is very unclear - it's written in language that might have specific meanings in JIRA and it's hard to see what you are really asking.
However, from what you've said, I think what you are asking for is:
Is that right? If so, then you'll need code. It's not a natural thing to do, so you can't do it natively, you'll need a post-function to read the component lead and change the reporter. (Note that it's perfectly natural to set the assignee to the component lead - they're in charge, they should deal with the issue - and JIRA supports that off-the-shelf. But not reporter)
