Something like this.
STEP 1:
Choose an NPC to spawn, I will use a rabbit for example
.npc add 721
STEP 2:
Find out the NPC GUID
.npc info
STEP 3:
Move to the location you wish the NPC to move to then enter:
.wp add 'GUID' (without comma's) In my case its
.wp add 329920
STEP 4
Do this as many times as you like in different locations, once finished:
.wp load 329920
PROBLEMS:
If it doesnt work, as once or twice it hasn't straight away on my own server you can try this:
.npc set movetype way
Also sometimes a server restart may be required I have found
