Changing last name after i-485 interview

[Journey_gurl]

Hi! So, my husband and I went to my GC interview (2 years conditional) today. Everything went well and the officer was very pleasant. I have submitted my applications using my maiden name and Ive been wanting to change it to my husband's last name. Ive been planning to ask the officer that I want to receive my GC in my husband's last name but I totally forgot it!!!!

Can I still have it changed without having to go through the I-90 route??

Any advise???

Thank you!!
