keep clips real size and data while nesting

when nesting clips that are larger than the sequence frame size it is not possible to add movement keframes because Premiere "bakes in" their dimensions to the size of the sequence they’re nested into — so anything outside the frame gets cropped, and the keyframed movement gets very limited to what's visible inside that frame. this makes pan, scale, rotation, position keyframing not possible.. 

can you add an option to nest while keeping the actual size and the outside-of-the-frame images/videos info so that keyframing will be possible?

this will be a huge update!
