Adding "no save" to everything in one go

I have 100 or so object types or so right now in my project, and the thing is, many are decoration, solid walls, or those that don't really need to save.

In fact, I only have about 6-7 objects that I need to save. But since we have "no save" behavior", rather than "save" behavior, is there a way to iterate through all objects and add "no save" behavior? After that, I can simply just pick several of my objects that need saving and remove the "no save" behavior.

Create family with 'no save' behavior and add those objects there? Might need few families if you have many different object types.

Ar, that's better to a degree.

If you have such a small proportion of your project that needs saving, it might be better to skip the savegame feature entirely, and invent your own using WebStorage.

If possible, it would nice to be able to right-click an object to toggle the no save behavior on and off. It would be a few clicks faster and save a lot of time as our projects expand.
