Creating multiple dynamic meshes that are positioned relative to each other

Hello, I recently started experimenting with UE, and currently I am exploring the Geometry Script (so far I got the impression that this is the best way to do what I want) to in order to create multiple dynamic meshes that are positioned relative to each other. For example, I would like to place a long cylinder, I would like to place another long cylinder at the end of the first cylinder and rotate it 90 degrees. I used the “Append Cylinder” tool to create the meshes, but I cannot move the second mesh on top of the first one. In other words, I would like these multiple meshes to be topologically related to each other. How could this be done? Thanks!
