When topics are imported from a past teacher they say "copied from Jane Doe" - this can cause difficulty.
If a teacher leaves on less-than-ideal terms but another teacher wants to use their content, they wouldn't want that teacher's name to show up on their own topic page. It would be good to be able to suppress that text.
you can import the same topic into the same topics page, them remove the old one. Now it will show your name instead of the ones you copied it from.
