If what you mean is kill/delete several stretches
of text at once, where you provide the limits of
each such stretch, then you can do that with an
iteration.  "At once" here would refer to the
overall effect, but maybe you have something else
in mind?

If you use library zones.el then you can use
`zz-do-zones', which just does such an iteration,
applying a function to a list of zones (start +
end positions).  But for this simple an operation
you can as easily use `dolist' over such a list.
