Events+ PHP code equivalents for shortcodes?

I would like to create a page that displays an events LIST for the current group being viewed. I realize there is a shortcode [eab_group_archives] with an optional "groups" parameter. Unfortunately, I don't see how I could make it work like this:
[eab_group_archives groups="current_group"].

So, if there were a function call for this shortcode, I could leverage the "groups" parameter by passing it a value for the current group ID. I can create my own shortcode for this or a page template if necessary. I just need to know where to find the code.

Thanks,
Jeff
