Feature Request: Option to disable fan for initial layers when 3D printing

Sometimes, it's just impossible to get that first layer down without it warping and pulling up off the board.

In this case, it would be handy to be able to disable the cooling fans for the initial layer(s) in order to slow the cooling of the filament as it comes out of the hot end and decrease the likelihood of warping.

What version of Luban includes this feature and where is the option located? I can't find it in Luban 4.7.0

By using "All" filter, you can see the "Regular Fan Speed at Layer = 2".

By default, the fan should be off for first few layers (Initial Layer Optimization -> Initial Fan Speed = 0%), and starts to work at regular speed from layer 2.
