IOS – Create WPA2 Enterprise Wifi + Certificate Apple Device Configuration Profile Without a Mac

Bingo! you've already got it there in your question.

Your last item "Web clips Credentials and keys" should actually be two - "Web Clips" and "Credentials and Keys" in which case, "Web Clips" is the one you're looking for. A "Web Clip" is a home screen bookmark for a website.

From the Enterprise Deployment Guidelines:

Web Clip Settings

Use this payload to add web clips to the Home screen of the user’s device. Web clips provide fast access to favorite web pages. Make sure the URL you enter includes the prefix http:// or https://—this is required for the web clip to function correctly. For example, to add the online version of the iPhone User Guide to the Home screen, specify the web clip URL: http://help.apple.com/iphone/ To add a custom icon, select a graphic file in gif, jpeg, or png format, 59 x 60 pixels in size. The image is automatically scaled and cropped to fit, and converted to png format if necessary.

Got it.

Open the XML file in TextEdit (or some other XML editor of your choice).

Scroll to the very bottom.

Look for: PayloadDisplayName Orig Profile PayloadIdentifier orig.profile

Change these two instances Orig to Dup or some other unique name. Save file. Go to configurator > import > point to file - it imports as 'dup profile' with all other settings in tact.

(I suppose you could also make XX copies of the XML file and edit each one, but it is easier just to leave the file open in TextEdit, make a change, save, import, make a change, save, import, lather, rinse, repeat.)
