As far as I know, no. However, with 13 points/level you can easily keep 1-2 stats at max and have plenty left over for raising at level cap (10 for now, 20 planned... eventually). Cyber Punks on Zeng Shi can drop Augment-weave armor that doubles Soreness recovery (1->2 for resting/3->6 for sleeping), making training physical stats at the Ten Ton Gym much easier. Training can get all stats to the cap at level 10, but won't when the cap is 20, so I recommend saving your level up points.
For reference, Hard Workout, Run and Swim Laps increase Soreness by 2 and reduce Energy by 50. You can't perform an exercise you don't have the energy for, so normally you can only get 4 Soreness/cycle, so you only need to sleep once to clear total Soreness.
Level 10 = 117 stat points
13x10 - 13 (because Level 1 doesn't count.)
Level 20 = 247 Stat Points
Assuming 3 Willpower start, -97 = 150
Assuming 3 in whatever your other stat was = 53
Training will get you up to 95 of 100, so 5x3 remaining stats = 15
TL;DR
You've got plenty of points to keep 2 stats maxed when you level up. Willpower can absolutely be one of them.
