Add Loops to "apple loops" rather than "audio files"

Hi,

I am adding various apple loops to my ipad2 to use in garageband by following the instructions here: https://discussions.apple.com/thread/3866623?tstart=0

They are primarily .caf files.

I would like these files to show up in the "apple loops" area of garageband, so that I can filter them there by using the numerours fields. I assume this is possible, because this is how it works in the desktop version of garageband. However, when I add the loops in this way, they show up in the "audio files" area, which only shows a single unorganized folder for all things audio.

Is there a way of adding loops to the loops area, and preserving the filtering potential that is in the desktop version of garageband?

Thanks!
