Trying to understand dumb zwave thermostat functionality

I’m looking to get my first connected thermostat. We currently have basic non programmable thermostats for our two gas heat with ac units. My wife works 12 hour shifts that are inconsistent from week to week.
We currently adjust the thermostats before bed and after we wake up manually. This works OK, sometimes we forget. During the day we adjust the thermostats manually based on comfort.

What I want to know is if I set a simple schedule through the SmartThings hub to adjust temperature at bed time and in the morning, can we still make manual adjustments throughout the day and have them be maintained. Or while the SmartThings schedule try and override our changes during the day?

This is just to get started, I can see myself implementing more rules as I add additional connected devices.
