There seems to be a host token in the first line of a schematic: https://github.com/koson/kicad6-file-collection/blob/main/files/github.com/Yongxin-Lu/self_balancing_car/pcb/24rf_remote_control/24RF_Remote_Control.kicad_sch

The paper token was named to page in here too. This seems to be a thing of the nightly build used there.
