[Koha] editing cancelled orders

We would like to add title and author to some deleted biblios attached to cancelled orders so that those fields don't show up as blank in our reports. Is it possible to modify a cancelled order? We are running Koha 3.14.01. Thank you, Margo Margo Duncan, MLS Systems Librarian Robert R. Muntz Library The University of Texas at Tyler 903.566.7174 | mduncan@uttyler.edu
