Batch Import into Apple Loops

Hello,

I want to "convert" multiple samples into Apple Loops, indexing the Musical Key and BPM. I know how to do this for a single file, but if I try to export multiple samples into the Loops Library, I cannot select "Loop", "musical key", and "tempo" is set to "0.00". It only allows for the description to be chosen, and lists everything as a "one-shot."

I thought this would be much easier but cannot seem to find a solution. I know there is the "untagged" section of the browser, but I don't see why if I could import 1 sample properly, it wouldn't let me import multiple.

Thanks for any help you may have!

B
