st: multilevel mixed effects piecewise model with 1 unknown knot location

Hi Statalist,
Does anyone know of a way to estimate in Stata a multilevel model that
is piecewise, with 1 knot, at an unknown location? I'm looking for a
multilevel analogue to the single-level piecewise regression approach
for an unknown knot location that is implemented in the nl hockey
command and/or that's implemented on pp. 111-112 of Michael Mitchell's
regression/Stata textbook. You might call this "multilevel hockey
stick regression," "multilevel broken stick regression," or perhaps
"multilevel spline regression." Any advice would be greatly
appreciated.
Thanks,
Jordan
