I second the request for gen auto start.
I agree the lack of an emergency start button would be unusual, but if you don't have one, they're a very easy install, a great DIY project. All it amounts to is a heavy relay (a starter relay works fine) placed between the main and aux batteries. You push a button, the relay energizes, and your main and aux batteries are coupled temporarily. Bonus is it works both ways. If you find yourself unable to start your engine, maybe because you left your headlights on or something, this same circuit could get you out of a jam there as well.
