Is it possible to get back to 1-step UNDO in PS like before?

The current Photoshop 2019 edition features UNDO option with multiple levels to go back.

However, I got used to 1-step undo with CTRL-Z going back and forth so much that I find the current feature very cumbersome.

The thing is, I didn't use UNDO to just "undo" the operation but also to see whether the previous change(s) were better or not. That's why 1-step Undo was more like before-after feature that I now miss.
