iPhone App download problems

I tried emailing ChinesePod directly but I could not get through (my message was not deliver - another tech issue).

How can we download several "self study" lessons all at once? 

I am busy. I commute. I want to be able to download a bunch of audio lessons during the brief period I am arround wifi.

Presently, I only know how to do this by clicking at least twice for __each__ audio file I want to download. Furthermore, this often fails silently.

The content is good and the app is a good start but please find time to take the app from a 70% to a 99%.

Thanks.
