my suggestion is the best
The XPT or Leviton 16400 wire the line and the load together to provide constant power to the overhead fixture which will need either socket rocket(s) or an inline model such as XPDM or XPDF.
Then say you put the switch on house code M (for macro) and the fixture on house code (L)
Then you create some macro in AHP:
If M1 ON is received between 8am and 8pm, then turn L1 ON.
if M1 OFF is received anytime, then turn L1 OFF.
To make things more flexible, you could carry a KR19a keychain remote to toggle a 'state' such as (K1) Kids Sleeping ON and Kids Sleeping OFF
Then you would modify your macro a bit:
If M1 ON is received AND K1 OFF is true, then turn L1 ON
if M1 OFF is received anytime, then turn L1 OFF
