I agree, I have been working on about 30 OU's for over 2 hours! If there was a way to export the OU's and then allow me to select them, via Excel and import them in. I click, it scrolls, I scroll down, I click, it scrolls. I have to click Save once in a while as I am worried the hour + of work will be cancelled out if something horrible happens (save often).

You've obviously got the code to create these, at least promote the internal private functions to public so we can use them from powershell without reflection and becoming unsupported.
