[I thought I remembered being able to bring any object parameter into the schedule fields but on schedule settings I am only getting a list of 4 object parameters: Front Axonometry, A, Rotation Angle, Surface. Mentioning this in case I am missing something obvious.]
Click on the little triangle next to the 'Add Fields' button and choose 'Library Part Parameters' (it will be slightly different in versions other than 22).
Then browse for your library part and the parameter that you want.
