It's possible to keep layers after goz back to Zbrush?

This is another thing I think it’s not logic in goz. Displacement information can be transformed between Zbrush and other 3D software, why layers will be destroyed after goz back to Zbrush? Is there any way to keep layers after goz back to Zbrush?

I’ve been saving my project and ZTool w/ layers before using GoZ, and all the layers are saved w/ it when I re-open the file.
