Add photos to specific frame in multiframe chunk

[Evan]

Is it possible to add photos to a specific frame in a multiframe chunk? I expected something like the following to work:

Code: [Select]

chunk.addFrame()
chunk.frames[1].addPhotos(photoList)

But all the photos are just added to the first (i.e. 0th) frame. Is there some other way to add photos to a frame other than the first frame?
