Kensington USB - Upload Phonebook from laptop?

I read the earlier posts about the Kensington USB Bluetooth only allowing 1 entry to upload at a time, but it was the one I could find in town today (and I had a gift card at the store).

I've been searching around to see if anyone has succefully managed to upload multiple entries from their laptop using this device and uploading multiple entries in a single connection session.

Thanks for your help!
