Navigate back in multi level page overlay prototype

As far as I know, there is no way to navigate back in open overlays. I know we can do this by duplicating frames, but this is just another screen to maintain unless we want inconsistencies. Any hacks very welcome!

I need going to overlays (swap overlay) from 1 to 3 … but when I press arrow back (keyboard left arrow) I want to jump on overlay 2…
