Initial Mass Copy - Period 1 Additions to be excluded

Hi Experts,

I am facing following issue when setting up new FA TAX Book:

FA Corp Book current period - Oct'20

New FA Tax Book First Open Period - Jan'20

Initial Mass Copy from Corp to TAX requirement - Initial Mass Copy to capture all Asset Additions up to DEC'19 after which FA Tax Update will be run to adjust Cost and Acc Depreciation. What happens is that Initial Mass Copy is also capturing Jan'20 additions, which we would like to exclude from Initial Mass Copy, and reflect them in Tax Book through Periodic Mass Copy,

Is there a way to execute above scenario ?
