Fan Speed Tile Question

I am trying to create individual tiles for each speed on a 4 speed fan. When using the set speed to action, I only have 3 speeds available. Is it possible to add a 4th speed to the Action (on tap)? I tried using the custom speed option but that can not set the fan to a desired speed. I know I can do this with variables but was attempting to do it without.


Not sure if this will help, but here was some discussion about Sharptools, Smartthings, and the Modern Forms fan integration and some solutions that worked for some of us for fan speed and on/off control.
