How to change default Save Image node?

Custom Nodes
1

i wander how to change the default prefix “ComfyUI” to other customed prefix if i use Comfyui Desktop for Windows. i want whatever workflow i open, as long as i load Save Image node, its prefix is not “ComfyUI”, but about the generating date, what should i do? AI told me to create a new node to cover the original one, but it doesn’t work.
