how can I tell difference between leve 1 w/wo 30 days free?

Hello Jason!
I have a simple level one membership set up.
One straight Level 1 recurring and one with 30 days free then recurring. However, I have no way of knowing which is which when I look at their "roles". Is there a way to distinguish thru s2member? I can't even tell by looking at Paypal transactions.
Must admit I didn't think about this when I first set it up or I would have made one level 2 for easy identification.
Is there any way to list a report that displays members with one or the other option, that I don't see in the documentation?
thanks
