Yanfly upgrade stats for JP - individual cost based on class

[Kilitar]

Hello, 


I am using Yanfly job points system for learning skills and also for upgrade stats.

I can set skill price using skill note tag


Learn Cost: 100 JP


I want achieve separate "JP price" for each class and stat upgrade. 


Example: increase MaxHP  via


Learn Cost Eval  using  param (actor.atk using user._paramPlus[0] += 10;


Anyway my idea is, every class can increase MaxHP, but "price" varies.


Warrior can buy MaxHP for cheaper cost than Mage - as it is easier for him to train Constitution, Mage has cheaper cost for  MaxMP


I can duplicate every stat and skill for each class but it leaves me with possibly hundreds of duplications, so i am asking for help, if there is more fancy way to achieve this goal. 


Thank you very much.
