Node Restoration Method After Using *replacenodes API in HyperMesh Scripting

I'm trying to write a script to optimize nodes using the *replacenodes API. I want to calculate the difference in mesh quality before and after replacement to decide whether to move the node. However, my question is that when HyperMesh executes a script, it cannot restore the node to its original position. If I want to implement this concept of restoration, is there any method to achieve it?
