Code used mpcustomchipping_mpcustomchipping to long for bookkeeping (xCore)

[insaneCreations]

i'm very well aware that this is not a issue of the plugin, it works great.
But sinds we use it for 'Store Pick Up' our bookkeeping module (xCore) doesn't like that the code is to long. No this is aparently not there fault (yea right).

But is there a way for me to shrink this code that has been given.. can you please help me with this problem
