Create sbsar with specific image input paths from a sbs template

Hello !
I'm trying to find a way to create hundreds of sbsar files with specific image inputs each.
To give you some context, i made a tool in designer to help me retake a lot of textures.
I'm using it with substance Player but in the end it's very long to configure input textures each time.
So i'm trying to generate a specific sbsar for each texture (by changing input file paths) without the automation tool kit, but it seems undoable because the sbsmutator is no longer available.

If someone have an idea to help me on that, i will be appreciate.
Thanks a lot.
