Had another post about this but it was buried so I thought I'd try it again.
In advanced strategy, instead of there just being a choice of 1 push level, it could be useful to be able to set different push levels for each stint. For example, say you are starting a race on a ss stint of 9 laps and then doing a 14 laps on s. Obviously you would want a different push level for each stint and this wouldn't be possible for people who can't attend the races.
