So we used to also be able to pull blocks.
There was an issue with how I wrote this logic that caused no small amount of headaches. On a sheet of paper my idea was the easy solution.. Turns out Godot was like "No. I don't like that."
It was only after release I thought of a potential better solution, but its now too late, and none of our puzzles were designed around being able to pull a block, so its not a planned feature.
