jQuery Grid Plugin - jqGrid

As far as I have found, there is no way to specify the order of the default buttons. Is that correct? If so, you need to use custom buttons which is what we are doing for some of the items. We would like our buttons to be in a specific order, so, is there a way to make the call to show the default add/edit dialogues show from a custom button? (Basically we want the default button functionality from a custom button just so we can change the order of the buttons)

Thanks,
