life cycle of popup information headed for renderer skin

I see that when a popup is configured and a feature is clicked on, the "data" is sent to the infowindow. However, if a popuprendererskin is set, it will filter it through the skin before sending to the infowindow.

So, If I click on a location that has two features from two separate services, it will populate the infowindow with data from one, and put the previous/next buttons on there to toggle through the two selected features.

Now, in the popuprenderskin, It appears as if the commit properties is fired on initial click, an then again when you click the next/previous button(s) and recieves the "data" from the current feature.

Is it possible to get the information from "both" features sent to the skin at the same time? Or a way for the skin to "request" the data from the "next" selected feature? I would like to customize my popup to print out data with some of it coming from one feature, and other data coming from the other, but both in the same infowindow.

Thanks for any ideas,
