Using instance as boolean

Hi. I’m still learning geometry nodes, and I have a question. I’d like to instance a set of meshes, but only along the edges (not the points). Ideal, I’d like to do it only along certain edges (like maybe I make them as seams?)

Alternatively, if I could get an instance list that includes the pairs of points that define each edge…

I might not be asking the right question, but I’m still learning this.
