Distribute VAT to dynamic GL Account on Invoice?

Looking for information on if it's functionally possible to calculate VAT but have the amount/accounting generate to the expense account on the invoice distribution and not a static VAT account. 

Example: invoice for professional services for $10,000. AP bu is vat enabled and default is 20% taxable code. Invoice is entered for $10,000 and VAT code calculate $2,000 VAT tax.  Either the expense distribution is booked for $12,000 to professional services account with the VAT of 2k reported on the voucher, or $10,000 booked to professional services on one expense row, and $2,000 booked to professional services on another expense row.  In both scenarios - business would be able to identify 2k in VAT charges, what code it booked to, etc.
