item/ability help

I wasnt quite certain were to put this, well this place looked right to me.

Ok this ability/item is going to be used in two campaigns im workin on (my campaign and the pokemon one) in pokemon it will be a pokeball system while in my campaign its going to be something similar to a orb of protection,,, or sumthing.

Anyway

im wanting an item (if this is possible without to many,,,, hopefuly no trigs) that can pick up and store units (so like a pocket zeplin) except there wont be a unit that appears just store and unstore of units. uh I hope I made this request for help clear enough...

For this to work, its going to involve a trigger system, or atleast the way I do it would. Heres how it works. You use the Soul Trap ability for this, then change the art to Orb of Frost or Orb of Fire or whatever. So once you cast Soul Trap(which you'll rename to Catch Pokemon or something) You need a big enough map to fit a small section of map off with some space to place pokemon. Then you have a trigger system like this.

Event : Pokemon X health is below 45(or whatever number you want)
Player casts Soul Trap(Catch Pokemon) on Pokemon X
Condition : None
Action : Disperse Soultrap Effects, Spawn Pokemon Ball in Region X.

Of course you'd have to make custom balls for every pokemon for this to work, wouldn't be that hard though, all you need is to change the name of an Orb. So like... Orb of Bulbasaur, Orb of Zapdos... That kind of thing, once you got all the balls, then replace "Pokemon Ball" with say "Ball of Zapdos" if you were catching a zapdos, which had his health down to 45 or less.

There's probably a simpler way to do this with variables and stuff, but thats how I'd do it since I'm a bit noobish with variables.

ya know what thats a good idea
but one side note,,, will that keep there level and such and would I be able to recall the pokemon (you know like "return Bulbasuar" and it goes back to the pokeball..) without losing the level. other than that your system is very interesting. Im gonna look at it some more

ah do you know of that blue little bar with the time limit? i want to change the text in it. example: metamorphisis timer, avatar timer, summons timer (the blue bar with the text in it which has time)

This is just from memory, but look under Advanced>Gameplay Interface for thing such as "Water Elemental Life Timer". Change this text to whatever you want, and add that type of timer to the unit.

well anyway back to my question... Is there a way to use the game cache to save a unit then remove it from the map, and then restore it from the cache??
