Like this?

On notation, since jump methods tend to have relatively few and small
jumps, I like using (xy) for a jump from place x to place y (where
|x-y|>=2), and as usual z for zths place made, so e.g.
(13)4 denotes
23146587
(13)(31)8 or (13)(31) denotes
32154768
(13)(42) denotes
24136587
I think it's true (but perhaps not completely obvious) that there is
always at most one way to fill in the remainder of such a change with
non-jumping bells.
