Center location question/suggestion

[LogGits]

Could we get a feature that specifies how far out from a specific position? Instead of the current:

MaxXY: 10000
MinXY: -10000

Maybe a:

Min: 1500
Max: 10000

Where it does 1500 blocks out from the centre location to 10000 blocks out from the centre location.
If this is added, it would be good to have a admin command for it:
/wild [player] <min> <max> <centerX> <centerZ> (optional World)

I've thought about this and not really sure how to implement this cleanly without effectively changing the randomness. I think I may have just thought of a way...
