Parameter tuning in Xpc target

Hi,

I've recently been working on Prototyping on Target machines

I'm looking for advice or at least a point towards a best practice for storing parameters for several tests.

I have been using the method from the following example:

http://www.mathworks.co.uk/products/xpctarget/model-examples.html;jsessionid=48bc5c262080c44cb1ca2bc954f0?file=/products/demos/shipping/xpc/parsweepdemo.html

The problem I find is with large model with many parameters there seems no easy way to identify parameters that I want to change.

I have being holding the parameters in large data structures but this seems like a very labour intensive thing to do especially seeing if any blocks name change then large amount of data becomes useless.

Can anyway think of a better way ?
