Altru Ideas

In the shopping cart, is there any way to edit the text describing the fees? We'd like to call it a convenience fee (or at least have the flexibility to name it), but it looks like no matter what we call it in Altru, it appears just as the total "fees" under the item in the cart. We also we wondering if there was any way to explain why the fees--> we are doing a per ticket fee, but since there is no description of how much each fee is for, the shopping cart just shows $6 total for 3 tickets, which might seem high to our visitors who don't realize what's happening. Does that make sense?
