MyFishFinder.com Just like iceshanty but warmer
Michigan has the same three line rule and I've been checked a few times when fishing with friends who were using my equipment with my tags. Never had a problem with too many of one particular name tag - each time the CO's only wanted to know how many lines we had in total for the licensed fisherman in our group and never even looked to see if they were tagged. I would think you would be fine doing the tape/marker tag.
I would tape them since its easy. place piece of tape on flag wire. it stays on but easy to remove. I don't think mr green jeans would give him a ticket, if you were there, but you never know if his ticket book is full for the month or not.
