Smart Light Routine Can't Dim Below 10%

I have GE Dimmers that will dim the connected bulbs all the way down to 1% using the “Things” tab. However when setting up a Routine, I can only dim in 10% increment with the lowest being 10% brightness. Obviously this is an annoying and senseless limitation of the smartthings app. But I would like a way to set up a routine that will allow me to dim some bulbs down to 1%or 2%. I found some similar threads but no solution. Any help would be appreciated.

Use rule machine instead

What is rule machine and where do I find it? Thanks!
