[Modding request] Specific facial hair transition

Hey everyone

So I have a lot of CC facial hairs and although I have updated the tags so my sim can shave, the progression of growth outside of the facial hair you choose is randomized.

I want to be able to choose a specific facial hair for every growth level (0, 1, 2 and 3) and to be able to choose wich level to shave to.

So if my sim is in growth level 3 he would be able to shave to any level below 3, but if he is on level 1 he would only be able to shave to 0, and so on.

I hope this makes sense, any help would be appreciated.

English isn't my first language so if things aren't clear, don't hesitate to ask!

Thanks in advance
