Editor question : Reducing all unit profencies at once

[kutaycosar]

Is it possible to reduce unit proficiencies in general? I read somewhere in the forum that scenarios generally suffer from high profiency parameters and that this reduces the importance of supply. Is there a way to proportionally reduce the proficiencies of all units from the editor? For example, reduce all unit proficiencies by 20%?
