Several bounding boxes of varying height

I'm generating a report that will need to closely match a page with
several sections of text (different sections of a SWOT analysis on top
of each other). Each of these sections, which was going to consist of
a bounding box for the text, will be of varying size. To position each
subsequent bounding box, I'm guessing I need either the current y
position on a page, or I need to do a set of nested boxes, so I can
distance each one from the bottom of the previous one (of a dynamic
height).
Getting the current cursor position would be easiest, but I can't find
anything in the docs or here that mentions how to do that.
I suppose this could also be done with a table, but the formatting
requirements might make that impossible.
Thanks!

The current position (relative to the margins or the enclosing bounding box is)
pdf.y - pdf.bounds.absolute_bottom
I've yet to think of a good name for that calculation, otherwise I'd
simplify this.
Since bounding boxes move you directly below them even with dynamic
heights, it seems like this approach may work for you.
