[FO4] Help with simple FO4Edit Script (NPC height variety)

Hello. I have installed More Generic NPC Faces (since it includes facegens) and I would like to make the spawned NPCs more randomized.

NAM6 - Height Min = 1, and NAM4 - Height Max = 1 is vanilla values for all new NPC. I would it to be 0.95 to 1.05, that means all NPCs spawned will be between that value.

Can somebody help with a script like that? Thanks a bunch!
