[Koha] New Questions- Strike the other 2

[Sky King]

Sorry, I answered my own 2 previous questions.  Just had not searched long enough earlier.

Is there a way to change the classification to accept letters.  The two libraries I am testing this (koha) out for use the Library of Congress Classification system and I need the Dewey Field which corresponds to the Classification to be able to use the LC call number.
