The answer to this question I found is "no, the feature was indeed
available in 4.2.3 but just missing from that section of the docs."

And this was correct as well.

A followup question relates to the apparent requirement that you add
the RRD/test name to both the GRAPH and the TEST2RRD variables in the
hobbitserver.cfg. Is there any way to add the graph to just the test
page and not the trends page? Why do both of these variables exist if
it seems like you need both of them for it to work?
