need qick access to multiple play lists

[pejay]

My playlist in media library library is getting too large for me to add anymore headings.In this forum i have asked if it is possible to add another new main playlist to media library, or to put folders into folders as in windows. I assume that since I have had no reply it is not possible. What would be my next best option to have quick access to about 50 separate headings? need help
