Sweet mother of Arceus, IT WORKS!
Some notes: When I noticed my OR backup had no file extension, my natural tendency was to give it the .bin extension. When I tried to import my edited save while it had the .bin extension, the save manager app didn't like that. So, I removed the .bin extension, and it imported like a charm. I cloned my Event Shiny Rayquaza 6 times as a simple test.
IMPORTANT: I've only tested my OR, but I'm assuming, whatever filename the save manager gives to the backup file, the edited file has to keep the same name for the import to work.
