= Trac Ticket Batch Modification = [[TracGuideToc]] Trac supports modifying a batch of tickets in one request from [TracQuery custom query] results . To perform a batch modification, select the tickets you wish to modify and set the new field values using the section underneath the query results. == List fields The `Keywords` and `Cc` fields are treated as lists, where list items can be added and/or removed in addition of replacing the entire list value. All list field controls accept multiple items, such as multiple keywords or cc addresses. == Excluded fields Multi-line text fields are not supported, because no valid use-case has been presented for syncing them across several tickets. That restriction applies to the `Description` field as well as to any [TracTicketsCustomFields#AvailableFieldTypesandOptions custom field] of type 'textarea'. However, Trac version 1.0 supports more suitable actions like 'prepend', 'append' or 'search & replace' ([http://trac-hacks.org/ticket/2415 th:#2415]).
