This is a known missing command or feature.
The only easy way to do this is:
Export a sector sector from single player import to server. This will work.
(dont forget to turn protection back on, else you will have to reimport again every few hours because someone killed the npc there.)
Also the autoreplacement will regenerate shops in sectors that are unmodified, so in case of big servers, that have some sort of spawn building it should never replace or modify anything without manual actions.
