Default symbology when adding new shape

BeraAkamole

When i add a new polygon layer to my ArcMap mxd i want the symbol red and 80 % transparency by default and not random color and 0 % transperency.

Is this possible?

The application randomly picks default symbology colors each time you add new data to your map.  You can manually change the symbology through later properties but I don't think you can control what the app picks as a default.  Transparency is something you need to manually set within layer properties.  ArcMap won't automatically set transparency settings.
