Tax rate code to be derived based on GL account

Summary:

There is a requirement to derive Tax Rate Code based on GL account. E.g. Capital Tax Rate Code based on Fixed Asset Clearing account. I have configured Tax Determining Factor Sets based on Accounting as Determining Factor Class and Tax Condition Set = Fixed Asset Clearing GL accounts.

However the requirement is that additional GL accounts may be added as Fixed Asset Clearing accounts. New configuration rule, Determining Factor Sets and Tax Condition Set have to be configured for new Fixed Asset Clearing account since the existing Tax Condition Set cannot be edited.

Is there an option where new Fixed Asset Clearing accounts can be added to the existing configurations? Similar to a value set or lookup?
