Hi,

you could create the needed functionality by yourself - there is an opportunity to use our API. You could find more information here: http://kentico.com/downloads/kenticocms_api.zip
Please find the chapter CMS.CMSImportExport.

Maybe you could find some inspiration for writing the code in some files in ~/CMSSiteManager/Sites.

You could take an advantage of scheduling – please see here http://kentico.com/docs/devguide/scheduling_a_custom_code.htm for more details.

Best regards,
Helena Grulichova
