You can also select an object after you create it and place it on another layer, such as a no plot or hidden layer. I hope this makes sense!
In the image I have my alignments create their own layer when I create them, allowing me to freeze them and their labels, I don't have mine create a layer for each alignment layer, but it should work the same way.
