H4 Stamping based on H1 amendment

Hi,
I have my H1 extended to 2023, but my wife’s H4 is about to expire in September 2021. Now she wants to travel to India due to personal reasons and planning to return in December 2021 based my current H1 receipt number. Now I may have a situation during her stay in India where I need to start a H1 amendment due to client change. can she go to stamping based on current H1 receipt or should she wait until my H1 amendment is approved?

She can use either of your approved H1B application for H4 visa stamping.
