You were right - I’ve now actually labeled the schematic nets so the wiring around the motor driver is named instead of just implied. Renaming net designators is the correct project edit for adding wire labels in the schematic
Added schematic labels

If you want, I can do one more cleanup pass and rename them to match the picture even more closely, like:
  • AIN1
  • AIN2
  • PWMA
  • MOTOR_5V
  • LOGIC_3V3
Rename to motor style
