Add graphical references of potential use as evidence in legal proceedings in the context of the Chilean social crisis

Hello I hope you are well. I am Chilean and we will be one month facing a serious social crisis. Eventually graphic evidence will be necessary to resolve judicial conflicts with genuine justice. In order for it to really apply, it will be necessary to be able to add notes that account for the location, date and time of a video in a large database. Is it possible to do this on these maps? and how? In advance, thank you very much and have a nice day.
