Pufferfish subdivision upon specified axis

Hello,
I am currently working on a project in which I hope to utilize twisted box sweep and morph to twisted box. I am currently struggling to increase the amount of subdivisions in the original twisted box.
Objectively I hope to increase the amount along the ellipse(y direction) but not the amount along the length of the mass(x direction). I Used sub d tbox but did not achieve my desired outcome.




In summary I am trying to increase divisions of the tbox in the y direction and no other.
Let me know if i need to clarify anything…

Apologies for not adding gh file, It is very long and probably inefficient
