How to edit shared job's reference jobs?

Hi,

 

I am trying to edit the shared job's reference job. Highlighted part of the picture. Any support/insight on the below is greatly appreciated.

 

Thanks,

Prajwal

If you are using a "Read-only" Shared job, you can unpack the Shared job, edit the reference job, rename and pack it as your custom Shared job.

Thank you @AnudeepK​ . After a lot of frustrating trial and error, I was able to figure this out quiet some time ago. Appreciate your response.
