windows media player 11 multiple cd burning

i have several cds worth of tracks i want to burn. i have them all in seperate folders because they belong on seperate cds. if i put too many tracks in the burn list at once it automatically moves ones that cant fit under a new dividing line labeled "next cd." i would like to throw all the tracks for all the cds in this pane and have them all aranged to go on the cds i want to, but the only way i can find to make it generate this next cd function is to completely fill the first one. is there any way i can designate the start and end of the cds so i can have them all in the same pane, divided by cd, and just keep removing and reinserting cds, so i dont have to go back and forth clearing the burn list and putting the new tracks on it?

 

heres a screen shot

as you can see, it moves them onto the next cd when the first one fills up, but when i try to drag the tracks i want on the second cd to the next cd directory, it simply bumps up the first track from the ext cd onto the first one. how can i make it end that first cd with the last track and not just fill it up, while still having a next cd section full of the tracks i want on the next cd?
