Start matrix loop from block ID Is it possible to start a matrix loop from a particular block ID?

I am trying to set a new block called "New Page" so that an author can split an article into multiple pages.

Currently it's able to detect a page break and exit out of the block field loop. I have also identified the next block's ID.

{% set nextBlockAfterPageBreak = contentBlock.getNext().id %}

Now what I'd like to be able to do is to get all blocks from nextBlockAfterPageBreak.

So for example,

{% for contentBlock in matrixField where firstBlock = 237 %}

Does anybody know if this is possible?
offset works for matrix blocks the same way it does for entries.

So you can do this to skip the first 12

{# skip the first 12 blocks #}
{% for contentBlock in matrixField.offset(12) %}
  ...
{% endfor %}
