Resize UV elements from their own center, not average center?

#1

Hi, I have 2 million polygons like this (all “broken”, not attached to eachother),
I need to resize them to infinitely small. How can I do that?
If I just select them all and try to resize them, they will just be resized from the center pivot of selection, not individually
