Is there a way to make an option amount taxable or nontaxable, depending on if a certain stream is u

This is the criteria from customer:

If the contract uses the following stream:

CAT OPTION FEE PXF stream, then you want CAT QUOTE CONTRACTUAL FEE TAX to be used (so that it taxes the Cat quote Contractual Fee).

 

However, if the contracts uses:

CAT OPTION FEE PXF - NO TAX stream, then you want CAT QUOTE CONTRACTUAL FEE to be used (so that it does NOT tax the Cat quote Contractual Fee).
