You can generate a block of a section from a "Section Object" by right-clicking and selecting "generate section", then move it to a different elevation and generate another. Then you can move the blocks away from the model to avoid needing different layers per viewport. The downside is they won't be associated to the model (IOW, changing the model won't update the views), but at least the views came from the model and your layers can match your standards. You may need to edit the blocks, or explode them to get everything looking like you want it.
