How to manage spawn rate

Hi, i was wondering if it's possible to edit the spawn rate of vanilla spawn point , so when the server wipe it can switch to the new spawn rate , i'm asking this cause i know i can do it by hand and create spawngroup and everything but if i do so if the map is wipe since monuments are not located at the same place i'll have to redo everything by hands 

thannks

This plugin does not currently support modification of vanilla spawn points.
