Looking at, eg,
lilypond-2.19.44-1/lilypond/usr/share/lilypond/current/scm/music-functions.scm
I read:

"The @var{laziness} is the number of measures
for which reminder accidentals are used (i.e., if @var{laziness} is zero,
only cancel accidentals in the same measure; if @var{laziness} is three,
we cancel accidentals up to three measures after they first appear."

which seems to imply that setting laziness > 1 will do what the OP
wants and is all that's required.

I have no idea how one would do this nor where laziness gets its
default value from.

Cheers,
David.
