subnumber asset

I have one asset A1, subnumber 0 with asset class ZFA1, this asset has acquisition value of 100K with local and group depreciation area, I have another asset A2 with asset class ZFA2,this asset has acquisition value of 30K with only local depreciation area,

is it be possible to create a asset A1, subnumber 1 , but only have local depreciation area like asset class ZFA2?

Thanks
