[Koha] Question about Fines Set-up in Koha

In the StaffClient program, in the patron's account, under Fines, under Create Manual Invoice There are several types to choose from, such as Account Management Fee Cancel Credit Checkout Fee etc. Is there a place/way to create a new type of fee (or even to adjust the current types)? Thank you. Sally Bannen Adult Services/Cataloging Librarian Windham Public Library Windham, ME 04062 (207) 892-1908
