Multiple cost centers change through Substitution in Asset Master

Dear All,

I know, we can change the one cost center  for multiple assets through substitutions but Can body please let me know are there any way for  Multiple cost centers change through one Substitution  for multiple assets .

or we need to use the LSMW

And what will be the impact if we take valid from date is  15th November  2014 for new cost center and how system will calculate the depreciation for Old cost center and for New cost center

For example:

If we take new valid from date is 15th November 2014 for A (New cost center) automatically B (old cost center) last date will be 14th November 2014

Here how system will calculate the depreciation for Old cost center and for New cost center and any impact ? if we suggested 15th November 2014 to business for new cost center

Or

we can suggestion 1st November or 1st December  2014 for new cost center…

Kindly provide your  valuable suggestions.
