Should we revise DS 160 if we get a new I-797 while waiting for stamping in India?

We are currently in India. Our dropbox appointment was in early March and our passports were returned with white 221G (asking us to attend interview). We can walk-in as soon as consulates open. We do not require a new appointment as per 221-G document. Meanwhile, my firm has applied for my H1B extension and we are anticipating approval soon. Once approved, I will get a new I-797 with consular process. Assuming that I will receive extension approval by the time consulates open, do I need to submit a new DS 160 when I walk-in for my interview?
