Suggested tip on split by seat checks be for each seat and not the whole check

We had a merchant notice that when they did a Split By Seat, the suggested tips on the CC receipt were based on the whole check and not just that seat. I explained they would need to split by check to avoid that because split by seat is still one check and that's why it does that but they asked me to submit a feature request. I think it would be nice if it worked this way.
