Image uploader custom field in CustomPress?

Hey all,

I'm working on a client project post-type, and was expecting to find a custom field that would allow me to upload images (which I'd be able to position at points through the page through the magic of HTML/CSS). I've been poking through CustomPress, but no luck. Am I missing it?

I've verified that Advanced Custom Fields has this functionality; it seems like for all CustomPress is set up to do, this is a strange shortcoming.
