Can I make a tax rule based on the Party Site Fiscal Classification

Hi,

I made a rule to apply a different tax rate to customers with a specified Party Fiscal Classification, but found out I need to apply it only for specific sites of the Party and not all of them. When I change this configuration to assign the Fiscal Clasification for a Party Site and not the Globarl party configuration, the tax rate for the specific site is the default one and not the one I assigned with the rule. Is there a way to create the rule for the party site fiscal classification?
