I love that idea. I've heard it a few times now and have brainstormed a few ways of doing that. I'm not entirely sure how it would be done at this point. My thoughts are that it could be done at the condenser-interface level.
For example, Steempeak allows you to create a posting template with beneficiaries pre-filled in. I wonder if we can do something similar, but somehow automate it based on the referring account. It's a tough task, but maybe we can get something installed one day. I'll talk to my dev and see if it's a possible integration for SteemLeo.
