Yes there is, all u have to do is for the trigger that activates the respawn script, make it only activate once, rather than repeatedly. However there is a way to get ur guys to respawn repeatedly after the waypoints have been reached, create a trigger that activates the respawn script, with a condition of alive player etc (i.e player being the name of the guy uwant to respawn) and syncronise the trigger with the waypoint that u want the respawning to begin at.
