Well you can open a default template for that, but there are a bunch of other things that should have a preference.
Collision polygons for example. I don't need it to guess the poly, until I need it to guess the poly.
Or text objects, set to center, bla, bla, bla....
But I can't really make my own template that's a thing. In C2 I could create a new project, set it up as i like, save it in C2\templates folder and add it to the startdlg.xml file. So every time I create a new project, the file I created, set and saved will always open, with everything already set for me.
I can't do that in C3.
