Change of status to H4 + H4 EAD concurrently

I am on H1B and applying for Chang of status to H4 + H4 EAD concurrently. I am sending both H4 + H4 EAD applications in one envelope to USCIS. Please guide me where I can mention that I am applying concurrently.

Your question is unclear. Why would you write concurrent if your spouse has H1B approval?
