Best way to automate creating pathfinding nodes?

I’ve been using the plugin https://www.roblox.com/library/2782420143/Node-Connector to create pathfinding nodes, which is easier because they’re all in the form of parts so I can easily move them around.

However, I can’t copy and paste sections of nodes or lock them to a form of a grid so I have to do everything manually which would take tonnes of time. I would like to know if:

-There is a way I can get around this (for those who have made huge node grids for pathfinding what did you do?)

-If there is a way that I can use PathfindingService to plot all these points for me and then move around the ones I want.

I am aware of how to use PathfindingService, but how would I make it plot points within an area?
