Container Groups to Snippets

Hi.

Consider this:

The pic shows four snippet memories (F1 ...) sequentially dragged into Structure, and then grouped into a section (S4).

When S4 is dragged into the Snippets Matrix, it lands there seemingly OK, but when playback is attempted nothing is heard.   When examined, the created snippet  is seen to be empty.

This seems to be the case for all "higher level" structures where it is attempted to aggregate multiple snippet memories and put the aggregation back into the Snippets Matrix.

Now, I notice that I can make a Snapshot of the above, drag that to the Snippets Matrix, and have playback.  (Good!)     However, doing this replaces S4 in the Structure with a snapshot, which was not intended.  (The intent was just to get this thing into the Snippets Matrix.)

So, questions I have - 

Could it ever be feasible to drag a Group directly into the Snippets Matrix and have it land and playback correctly "automatically", as a Group?

If not, could we perhaps have a way to drag a Group into the  Snippets Matrix (SM) and have it land and playback correctly as a Snapshot in the SM, without changing the originating Group in the Structure?

Also, it is not entirely clear to me if the Ctrl-G operation which created S4 made the F blocks children of S4 or not.   If not, then an operation that does that would be quite helpful.
