Is there any way to update the position of the slots via importing json data once everything has been animated?

Essentially I started off with one setup via import from Photoshop animated it all and then realized it was the wrong size. I went back into Photoshop fixed the sizes and then pointed to the new images but the problem is all the slots were now in the wrong positions. If I were to regenerate new json data is there anyway to import it so that it can update the old rigs positions maintaining their animations?

Thank you in advance. I'm really digging the software!
