Create a new template option that does not package data. In ArcMap, I saved an MXD to the AppData folder on my C drive that contained templates. That MXD referenced a geodatabase, but contained all the layer styling and page layout I wanted. In Pro, it appears that creating a template works a little like a Map Package did in ArcMap. I wish to have the option to only create a file that a new project can be created on, retaining layout and map styling but not duplicating data.
