Zooz switch timer options?

First, I’m new to SmartThings after being a long time Wink user.
I’m trying to find a way to set a light/fan switch to turn off after a set time.

I have the Zooz Zen26 switches. There is a timer option in the app, but it looks like you have to set it every time you want to use it.
I’m looking for a way to auto turn off a switch for example 30 minutes after being turned on.

Is there any way to accomplish this?

There is an obscure option in the Smart Lighting SmartApp called Power Allowance that allows you to set a device to turn off after a set amount of time.

Unlike the more obvious Timer setting, Power Allowance is persistent.
