Thought for a moment

I inspected the current part project and confirmed it contains 25 terminal pins for the MAX17320G20+ symbol, all currently with Pin Type: Unspecified and no functional Pin Group / Section assignments.
Found current pins:

I attempted to retrieve the MAX17320 datasheet pin table from the project datasheet source and from Analog’s public PDF, but the text extraction did not return the pin table before execution stopped. Remaining work is to manually extract or upload the relevant datasheet pin-description page, then update each terminal once with a unique functional grouping such as Power/Regulator, Ground, Cell Voltage Inputs, Current Sense, FET/Pack Control, Thermistor/GPIO, and Digital Interface/Alerts.
