You don't ;)
POV-Ray does "add" media together wherever media containers overlap.

You're right about media /settings/, such as sampling method, number of
samples etc.

I have a hunch that a `merge` of media containers would screw things up
big time; to properly handle overlapping media containers, POV-Ray needs
to detect each and every surface of each and every media container; a
`merge` suppresses detection of any of its children's surfaces that are
inside sibling objects.
