Microchip releases new chips every few months. The 24F family is relatively new. Schematic and layout programs were written before the family existed. The GB is a new addition, so you will have to play the lead lag game if you want to relay on these softwares. Otherwise just make your own symbol. The softwares I used have never been equipped with any microchip parts in their libraries. I am looking at your request as alien in my eyes. Shocked you ever had a microchip part you have not fabricated.
