Struggling with building my vocabulary to sync with my iphone.

Hi,

I'm sure I'm missing something simple here because it can't be this hard! 

I would like to build up a vocabulary of characters that correspond with the characters I need to learn for university. 

I've made a label called 'Unit 9' and I searched ChinesePod's glossary to find the characters I want to study. For example I looked up bie2 别 and found it amongst other characters in various combinations but I can't find a way to just add that single character to my vocab list. 

In the past I've used the DianHua app on the iphone as I can just do a dictionary search for any character I want and then study them with flashcards but I wanted to switch to the ChinesePod app so I could then go online and use that same vocab list with Scritter.

So, long story short... How can I just search for single characters and add them to my vocab list?

Like I said I'm sure it's something easy I'm just overlooking!

Thanks in advance!! :)
