Can I update in Input files and directly select nodes and make again Process?

Is it Possible as I am doing while preprocessing steps those same steps can I write or update in my Input file like node ID Or element Id and I can see the Change in my Geometry?

I want to apply MPC constraints to each of my node, like one Dependent and Another Independent  and those data I want to just copy paste from my known data.

I know the node ID Or Number..

Please guide me How can I do it...

Thank you,
