DOWNSCALE'S PROFILE

Hello, new here, new to RPG Maker VX Ace too... my question may be simple I dont know....

I have a bunch of custom items but i would like to reorder them without having to remake the list... I also would like to easily be able to reorder them in the future as needed...

Example: Is there a way I can move "009:Life Up" to become "001:Life Up" but automatically move everything else down a number? so then "001:Potion" would become "002:Potion", etc.
Thanks!
