An equivalent feature already exists - the
"Excel" (TSV) survey export.
Simply do the following:
(1) Export the survey in TSV format
(2) Open in Excel (launch Excel, select open the .tsv file, and tell Excel that it is UTF-8 format when you open it - double clicking the file name seldom works).
(3) Make all of your edits. You can use Excel's find/replace if desired
(4) Save the file in the original format
(5) Import the TSV file back into LimeSurvey. This will create a new copy of your survey.
You can use this approach to make as many bulk changes as you want, including re-arranging questions, adding/deleting/editing them, or even adding/reviewing translations.
