Building a persistent navigation

One of the requirements of my project is to have a persistent navigation element that stays in place as the user linearly goes through the scenes. It seemed like a Persistent Symbol would work for this as it does not move away during scene transitions. However, there are more than one responsive layout, and when I adjust the elements within the navigation for one layout, it moves in all the other layouts. How can I have an element persist during scene transitions yet be able to adjust containing elements per layout. Is this even possible? Help much appreciated!
