May We Please Have a Way to Bypass CAS?

And while we are at it, can we also get an option to opt out of getting our newly created households saved into our library? For safety reasons the default should be to save the household, of course, but there could be a checkbox that we can uncheck if we don't want that.

I have a "Townie starter kit" household that I use everytime I start a new save, and every single time the game places a new copy of the bunch into my library.
