I-140 amendment to include spouse

[Nzfh]

Hello,

My husband has filed I-140 under NIW category last year. Both of us also submitted I-485. I did not apply for AP and traveled out of US, which means my I-485 is abandoned. His I-140 is still pending. In this situation, is there any way to amend his I-140 to include me as a dependent and hence making a way for me to go back to US?

Thanks in advance.
