Yes, indeed it looks like this is available by default (you don't even need EXTENDED_GLOB).

d,1([^[:digit:]]*|)(N)

The (either_this|or_that) matches either what you originally said or nothing ("or_that" here is empty).

There are other ways of doing it, and there's a ksh/bash-compatible way, too, but that's probably
the one I'd immediately reach for.
