At the moment, I'd love Pun to become really strong with her attention to details and also work on her English language skills, how to use it - especially when communicating with clients.
(Although she's not communicating much with clients at the moment, I'd love her to seek out the lessons - through others' tickets, asking for advice from team members, etc.)
This is really the time for her to acquire such qualities before she gets fully trained as a Newsletter Producer. When the time come, she will be one of the strongest producers, with a solid ground to stand on.
Don't rush through it. Don't feel that need to do so, she will find out how valuable this time with repetitive tasks is as she continues working here.
