DCP DCI Naming for Composition Playlist

I'm getting told by a theater that the DCP I wrote is good except that the naming convention for the Cinema Playlist should be in the standard DCI naming convention. I see how to name something using that convention, but not where to do so with the DCP I created in Resolve. Is this something you can just change in the naming of the files after the fact?

Are you using the composition name generator in the deliver page?
