Parenting Cut Out using Harmony Stage

Just purchased Harmony Stage and am getting my feet with some cut out, however I’m having a bit of difficulty figuring out how to parent some of the pegs together in my cut out using Stage. All of the tutorials on the site seem to be using the Node Panel, which is non-existent in Stage. I’m thinking there must be an easier way. The layering makes perfect sense, but there does not seem to be any other way to parent the pegs and layers together. Any help would be appreciated and/or tutorials someone has found that deals with the basic version of the program.
