I don't think that's practicable either. How should MSP know if the one pdf is a collection or just one sheet for one audio.
But you are aware that you can select all of the audio files in the folder at once to add them to the pdf? Shouldn't take too long to do this for all your collections and doesn't warrant a specific batch import option for your user case IMHO.
