Windump default interface

Does anyone know how to set a default interface for windump to use. My problem is this: if I execute a windump without -i 2, I get an Ndis interface (which I am not using). For some reason, the only ethernet interface I have is not the default. If I use Ethereal, I can specify the default interface when using the application so I don't have to specify it every time I go to use the app. While specifying the interface is easy enough, it's a hassle and sometimes I forget to do it. I'm just wondering if there is a solution for this that anyone has heard. Any ideas, or should I just stop complaining and move on? lol :D
