Does not answer your question but a couple of thoughts: (please just ignore if they don’t make sense to you)
Have you considered dimmers for some of your switches?

GE Switch vs. Dimmer - Toggle Variety

I use GE dimmers and regular GE on/off switches. A couple of thoughts: Dimmer switches have two actions: short press (=on/off) and long press (=dim up/down) Dimmers remember the dim level when turned off. E.g. in the bedroom I keep the level 50%. so when I turn the dimmer off and on again it does not brighten more than 50% (or you can set the dimmer to turn on at a certain dim level using an app) On/off switches also have two modes: single tap and double tap (2 taps within about 1 second). Single tap just turns on/off. For double tap, there is the “Double Tap” app that allows you to turn on multiple switches when you double tap. (the dimmer does not have the double-tap functionality)

I see that you use many switches. Have you considered door sensors to activate the switches? E,g my light outside the front door turns on when the door opens after sunset…

Smartthings lets you control other things besides just your lights: garage door (yeah, I know currently not 100% working), water heater, moisture sensor, doorbell/mailbox/washing machine (using an acceleration sensor)… Most of these can be done with the standard Smartthings apps.
