I agree that every part is different, unless it is the same part that you just want to change some setting in configuration.
If I could save some type of file with layer specification for specific models it should be nice.
Something like, for example, a native file for slic3r. Lets call it as a .SL3 file that maintain the geometry and these variable layer settings.
So, when I call this .SL3 it brings back the model and special layers condition.
