Multiple Persistent level with common sublevel

I have a question about the multiple scenario lighting, I would like to have your advice:

I have 2 Persistent Levels with multiple sublevels.

**Persistent Level**
- Lansdscape
- Sub level 1
- SubLevel 2
- Sub level high quality

**Persistent Level_VR**
- LandscapeForVR
- Sub level 1
- SubLevel 2
- Sublevel low quality

Some of the sub levels are duplicated, but if I made a change in one I have to make a change in the other… it’s not a consistent workflow

How to have a consistent wokflow?

Thanks for your advices.
