Is it possible to add my maiden name and how ?

I am an Italian citizen and I married an American citizen about 2 years ago, in America. In the marriage certificate I took his last name and dropped mine but in Italy this is not possible. You have to keep your maiden one so this is what I have in my Italian passport, bank account, license,.. This creates a lot of confusion especially when I travel and I would like to know if it possible to change and add my maiden name next to my husband's last name. It would be first name, my maiden name, my husband's last name. If so, how do I have to proceed ? Thank you in advance
