Go inside portal - Becomes level 1|Go outside becomes original level|Save-Load level!

I got a challange/request for all the scripters out there

1. if you go inside the portal you becomes level 1, and when you go inside another portal you'll become the original level again.

2. save/load level in a certain area.

example:
I'm level 54, if i'm
frompos="1000,1000,7"
topos="1100,1100,8"

if i'm inside that area i can save my level on 3 different slots. I can also load one of the slots. Then i recieve the level ( and if possible the items )
Thank you in advance,
