Save all instanced static mesh instances in game for a building game?

I got lots of progress with my game, and saving the location of static meshes was easy, but I converted to instanced static meshes, and saving them is a lot harder. I used this post: Saving "Instanced Static Mesches" to SaveGame - Blueprint - Unreal Engine Forums

but it didn’t work for me (probably because the ISM components are added dynamically in my game, if you choose a new material, it adds a new component, new shape, new component, and so on) so I need to know how to save the locations of all instanced meshes in the level. Any help is appreciated. Thanks in advance.

I was able to improve the instanced static mesh system, but still no saving. I am really hoping someone knows what to do here.

I have the same problem, do you found a solution?

I am having the exact same issue, did you ever get this figured out???
