methods of importing to UE4

I devised a method for importing all my assets into UE4 without missing anything in my Maya scene. I did this by creating an identical scene file in Maya, and I simply exported an asset then instantly deleted it from the copied file. By doing this I could identify what I had possibly forgotten by what was left in the scene. Doing it this way not only prevents me from forgetting assets, but it also prevents me from exporting junk or duplicates into the UE4 scene.
