avoid local alteration on iterative instances

$

hello,

I am running a monte carlo simulation (local mismatch only) and I would like to skip local alteration on iterative instances. 

for example, let us consider a current mirror Imaster<2:1> to Islave<4:1>.  I am interested in treating this mirror as 2 devices only (same as it would be when using m=2 and m=4 parameters) and do not apply local alteration between iterative instance, eg. bteween Imaster<2> and Imaster<1>, since these instance are anyway connected in parallel.

background of the question is to reduce simulation time, due to large input file generation when calling a monte carlo simulation on large circuits where many iterative instances are used. 

thanks, 

Giovanni
