Wenn ich das richtig verstanden habe, ist das in der aktuellsten Bambu Studio BETA schon mit drin, sollte dann also auch irgendwann produktiv kommen:
Edit filament information during printing : P-series and A-series printers now support editing filament information during printing, even for filaments not currently in use or in ‘Auto-Fill’ mode. This includes both external spool slots and AMS slots. Users can replace an empty spool before it’s fully consumed, and the new spool will automatically continue the current print.（Supported P-series firmware version:01.07.00.00,supported A-series firmware version:01.04.00.00）
