Hmmm. Only "perhaps a little more cumbersome"?
Let's take one of the conceptually simplest jump methods, jump cyclic. On 12 bells, the rows are:
1234567890ET
234567890ET1
34567890ET12
etc
So under your notation system, every change would need to be defined by 11 plain changes, ie (34567890et.14567890et. etc etc as nauseam).
Consequently I think this would rather uniquely have the spectacular achievement of the notation system being longer (indeed very considerably longer) than a complete enumeration of the rows in the method. And be far from unique to boot.
My vote would be for one of the other notation systems :-)
