can the list of subscribers be sorted?

I just set up a Smartlist mailing list, and although I have the documentation I'm still pretty lost. Last night I sent out the first message to the list and of course lots of the emails bounced. I now need to unsubscribe those addresses. I already have hundreds of addresses and expect to eventually have over 1000. How do I find the address to which I need to unsubscribe? I found that if I type in the first letter of the address an address beginning with that letter pops up, but then I have to keep doing this over and over to eventually find the right one. There must be an easier way? Thanks! Lynn
