Our audio wall is running out of space in some category (1000 carts for the noughtys) we need to add more to this category but they are soon going to crash into the 2010 and so on  category. I just wanted to ask if its an easy task to add more blank carts and what the best way to go about it was. as say for instance the noughtys category runs from cart number 2000 to 3000 and from 3000 the 2010 and so on category runs up to cart number 4500 if I add more empty carts to the noughtys category then does it just push everything else down within the audio wall?
