Modular Actor Workflow?

Hello all I have a question that may have been asked many times but here goes. I’d like to set up a template for a house created by a bunch of modular pieces, and then be able to spawn it in game like an actor. I started out using the level editor and then once I had something I liked, I used the merge actors tool, but this didn’t really produce what I wanted . The only way I’ve found to do this is to use a blueprint with child actors and static meshes, but I find this workflow kind of unwieldy due to the lack of organizational tools in the blueprint editor (in general its just harder to work with than the level editor). Does anyone have any suggestions for this type of workflow?

So what are your expectations? What you actully want from this workflow?

Are you looking to import already-built pieces of buildings, and then work with them in the editor, or are you looking to generate a building from pre-made pieces during runtime?
