Reply to S4 remix deck question.

I have track decks for A,B,C and deck D is a remix deck.

If im playing a track on deck B and i'm looping a track over 8 beats and I hit the first button in the "samples" section, that 8 beat loop now becomes an 8 beat loop in my remix deck.

Now, when im playing a track in deck A under the same conditions (8 beat loop) and I use the shift key and press the 2nd button along (or whatever button in the sampling section) I dont get an 8 beat loop, but the whole track then becomes a remix sample.

Is what im doing possible?
If yes, why isnt it working?
If no, do I also need deck C to be remix deck to achieve what I want to do when attempting to capture an 8 beat sample in the remix deck on deck D?
