In admin/tool/uploadecourse there are several possible points where you would want to have options of the finally created course be taken of.
Should the ones of the template course be used, or the ones of the CSV file, or the ones of the user interface or the ones from the configuration defaults? To sum that up. What preceeds what? Is it always CSV > Template course > upload UI > CFG defaults?
As Eloy Lafuente (stronk7) states in [his comment||https://tracker.moodle.org/browse/MDL-63268?focusedCommentId=677565&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-677565] maybe there is the need for a option to steer what information has to be picked from what source.
