Change disc #s

[bobcox- with the Lord]

when i download disc into hoster database #s are diff then the ones i norm use, such as CB60020 I would norm remove one of the zeros CB6020. when i try to change them in hoster it adds a zero on the end. CB60200 is there any way to change this my books are edited for adult, duets, solo, trio, ect,, and printed out of music book deluxe. the data base will not match my books.
