IS Using a template Waitlist Update Bad?

I have done my research. I have made educated decisions regarding the offers I have at the moment. That said, I still want a wider pool of options which is why I have chosen to remain on these waitlists. I just want an opinion on whether specialising my writing matters. I do have accomplishments that I think may be worthy of updating the colleges about (where I am from my sporting seasons have just closed so I have awards, research work I hadn’t mentioned before because it was too early days, etc) .
