Find A Grave does exactly what it says on the tin. It is a site to help find the gravestones of loved ones. it is not a site for recording burial records without gravestones. There are plenty of other online sites that hold these details.
I will include all relevant details for an individual only if they appear on the gravestone, and I will not add suggested edits for maiden names, dates of birth, marriage etc.
Sorry to sound negative, but that's the way it is, and apologies if your suggested edit gets declined.
