Yes, you'd just use the syntax above. The library would interpret the above
as

DB1.server=172.16.21.1
....
DB2.server=172.16.21.1

In other words, it would prepend the name of the section to the name of the
option.

For your use case, you might want to look at one of the examples:

  http://zigzag.lvk.cs.msu.su/~ghost/boost/libs/program_options/example/dynamic.cfg

which unfortunately is not committed yet.
