Ahahah 
! I knew it 
!
FormulaMap() is a formula I actually have a hard time to “re-learn” how to use (correctly) and when. But I’m getting there !
I was pretty certain while building my example doc that I should’ve looked in that direction but I just couldn’t find a way around it…
This is, like always , a way better and prodigiously simpler solution to my initial problem 
!
Thank you very very very much for taking the time to look at this 
!
I’m gonna try and implement it to my doc right away !
