make a parent-type and child-type token available to pathauto

I am using NodeFamily to set my parent-child relationships.

I have an Image cck content type containing an imagefield. An Image is always a child of either a Blog entry or a cck Album content type.
Using pathauto,
I would like to set the Image path according to it's parent (Blog or Album). I was looking for a [parent-type] token, but there isn't one.

So, I could just do something like: [parent-type]/[parent-title]/[child-type]/[child-title] or some variation.
Pathauto has some tokens that would work for this, I think the Referenced node title or Id would satisfy the [parent-title] and Node title or ID works for [child-title], but I am not sure about the other parts.

Would Node Family be the correct place to request the parent and child token support for pathauto?
thanks
