For non-recoverable or non-deductible VAT, is there a way to debit the actual expense account associated with the line instead of whatever is the tax associated with the tax code?

I saw one of the possible way : Custom GL lines! Custom GL line plugin, deployed for every transaction type where non-deductable TAX is possible to be entered, add two.GL impact line... credit expense and debit TAX

Isn't it possible using the Supplementary Tax Calculation suiteapp?

I am not familiar with Supplementary Tax App... and I am sure that question is right for NetSuite support (SuiteAnswers)
