In the vein of keeping things nice & cooperative, one technical method that would make sense to me (your mileage may vary) would be that
last-minute special interest claims are only accepted if the other candidates approve of that action. I.e. once the meeting has officially started, if somebody enters a special interest, have the other candidates for that talk click a nice little checkmark beside the special interest string to say “yeah, fine with me”. Well, obviously, that’s kind of the same result one could achieve by simply talking about it in the meeting. But when things get a little crowded / chaotic / lack of time-ey – maybe a little checkmark to click might be a little more efficient than working things out vocally? Only really, actually one would need to discuss the matter when not every other candidate for the talk clicked on that approval thingy in good time? Then again, I know I love to over-engineer.
