Storing and loading Editable instanced Arrays?

Hi. I use many editable instances of arrays that I customize according to level. How to save and load these arrays, because unreal often deletes these arrays and I have to set dozen in each Level new.

You can make the arrays part of a blueprint. Then, whenever you drop it in the level, the arrays are always set.

If that’s not applicable, then you can always put the in the save game, even from the editor.
