Depreciation for 168 / 179 / Bonus allowance

We have depreciation methods like "MACRS 30B MQ" which can be used to get 30% addl. depreciation in the first year towards either 168 allowance or 179 allowance or Bonus depreciation. (I am assuming we can use the same dep method for all three above).

When we use this method and run the depreation, the 30% allowance is added to the Accumulated depreciation amount. However, business wants to have this shown separately and it should not be part of the Accumulated depreciation.

Please advise how to achieve this requirement.

Thanks
