I'm trying to redesign an app I did by hand in Designer 2, and my server requires that I make a post (get doesn't work) for an orders/list call. In my original code, I have the following:

Code:
actionMethods: {
    list: 'POST'
}
Then I pass my parameters through extraParams.

I can't find any settings in the Ajax stores or proxies to allow me to do this. Is it possible?
