[CE U16] Item Type Import/Export Selection

Are any of the following possible when importing/exporting Item Types to Excel:

  1. Select specific Item Type Libraries & even specific Item Types within those libraries to import/export (besides selection or fence options)
  2. Let the program know if you want to overwrite existing Item Type Libraries and/or Item Types
  3. Let the program know if you want to append/add Item Types to existing Item Type Libraries

I have played around with the import/export Item Types a fair amount and haven't been able to find any options like above. If they don't exist then I think they should definitely be enhancement requests.
