Spline Weld

I'm also noticing with the spline output that it's using the each scatter point if it's interlinked more than once, as a new node/spline within Unity Splines. The only way I can make single base splines is to use interlink of 1 (welding doesn't seem to matter). It's not the end of the world but it's a bit tricky to make more complex controllable splines as whenever I add a node to control the point it outputs an entirely new spline. Any thoughts on how I could get all points in a connected spline to output as a single Unity spline? Or perhaps which script/generator would be the the one I'd want to consider customizing to do this? Thanks! (edited)
