save default properties of add object menu (shift+A) in startup file

It would be practical to change the default properties of the shift+A add object menu. I usually like to orient the object to the 3D cursor. I have to do this everytime I start a new file, for every object which is annoying. The same goes for the size of the objects which I find way to big. Please make it possible to save default properties for each object to the startup file.
