Pin Function Grouping

flux

Yes — for a motor driver like this, the cleanest way is to put each pin in exactly one functional group, with no duplicates. That matches the recommended grouping rule for non-MCU ICs: group by function such as Power, Ground, Input, Output, and Control
Pin groups

Table

GroupPins
PowerVCC (20), VM1 (24), VM2 (13), VM3 (14)
GroundGND (18), PGND1 (3, 4), PGND2 (9, 10)
Control / Logic InputsSTBY (19), PWMA (23), PWMB (15), AIN1 (21), AIN2 (22), BIN1 (17), BIN2 (16)
Motor Outputs - Channel AAO1 (1, 2), AO2 (5, 6)
Motor Outputs - Channel BBO1 (11, 12), BO2 (7, 8)

Recommended common-function names
If you want to normalize the names for the part symbol, I’d use:

Table

Common FunctionPins
PowerVCC, VM1, VM2, VM3
GroundGND, PGND1, PGND1, PGND2, PGND2
InputAIN1, AIN2, BIN1, BIN2
PWM ControlPWMA, PWMB
Standby ControlSTBY
Output AAO1, AO1, AO2, AO2
Output BBO1, BO1, BO2, BO2
If you want, I can next turn this into exact Flux Section and Pin Group values for every terminal so you can apply it directly.
