[R] [ICLR] Is it okay to reference an answer to another reviewer in a reviewer's response?

I am writing the responses to my reviewers for the ICLR. I had two reviewers asking a very similar question, and I'm wondering whether it is good to say to one of them something like "please refer to answer (4) in my response to reviewer xxxx" and then continue to tailor my answer to this reviewer, based on the reasoning offered in (4) for reviewer xxxx. Is this valid or should I just copy/paste the answer?
