Using Bambu Studio you can create custom profiles for different filament used in the AMS. Using Generic PLA+ as an example there is no default filament setting for this type in Bambu Studio but you can create a custom filament profile for the AMS with different temperature settings to match the filament.
If you use the Bambu Handy or Printer Screen you are unable to change filament settings, specify temperature for filament in the AMS. Yes you can change the temperature once printing has started but you should be able to set it based on what filament is in the AMS.
Bambu can you add the ability to adjust temperature settings (bed and nozzle) through the Bambi Handy app and the printer screen based on filament in the AMS.
