Multiple faces swap question

[mccabedd]

Am pretty new to this, so please forgive me if my question sounds dumb and obvious.
I am trying to swap all the faces on a character sheet. I am using my own blended model that I created. The idea is to eventually create a lora.

I load the following image, but the model only swaps out a single face. In this instance, the largest at the bottom right.
I have tried using the variable in the Options node, and played around with indexing, but just cannot get things to work.

Is there any way to swap ALL the faces?

Figured it out. Input_faces_index (for the above image) is: 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19
