Opening smartlock disarms the alarm

I recently bought the simplisafe system with smartlock and keypad. I am really surprised that the system does not allow me to have a separate code to unlock my smartlock but NOT disarm the alarm. As I live on a city street, I feel this is a material security risk to my family and property if anyone was to shoulder surf or see fingerprints on only the 4 numbers that I use!

When contacting the company about this issue, they stated that they make the assumption that nobody will look over your shoulder. I think this is a naïve assumption. I also think it should be a relatively a small upgrade/development to add the additional flexibility to users to have a separate code to unlock the front door only without disarming the system. This also wouldn't prevent people from using just one code, as the system is currently setup.

I have raised this with customer support as a change I would like to see urgently. If any of you have a similar concern, please also raise this with Simplisafe through Contact Us so that there is some pressure to make this change. Otherwise I'm going to have to dispense with the smartlock (which would be a shame given the price I've paid for it already... and the fact that I generally otherwise like the lock)
