Tax Books in FA

Hi

Below is our scenario

CORP Book linked with GAAP Ledger

Tax Book linked with IFRS Ledger (Secondary ledger)

Could you please suggest how do we deal with below scenarios

1) Can we update Asset Cost in Tax Book with any more feasible way rather than manually adjusting the asset in Tax Book ?

Is there something like we can update the asset cost while we transfer the asset from CORP to TAX Book.

Example: Asset Cost 100 in CORP Book but we want to capitalize only 60 in IFRS, so while we are transferring, we can update the cost rather than adjusting it manually later on.
