Linked layer for Scenes and objects collections from scenes

I often working in way where objects are in Scene1 from Scene2 as collection and this is due the "Group add-on" and many objects/internal collections. To manage some version of objects on Scene2 doing Layers (hiding some parts of object, eg. car and car without roof as cabriolet). Also sometimes want link the car as with roof and without roof as cabriolet to the city (both are very advanced with many objects as car and elements and city).

To realize this my idea is to:

• manage linked collections with Layers related to Scene as source of object (main functions are check-boxes what to render or not - show/hide).
• simple.. in object properties under instancing give option to inheritance layer setups

It's require addition function to parallel working on 2 different scenes and solve some problem

• Splited workspace with own scenes and layers?
• Blender must remeber the last active Layer when switching betwen Scenes not 1st as default

I often meeting problem, where have many collections as dirs on outliner to manage other collection, but depend of depth of this all, have problems to manage final render in case is different view than viewport rendering shading preview.
