Compounding taxes for UK market

Hi, I need to make quotes and invoices with two taxes.

It will be items subtotal
Then added tax preliminary 8%
then subtotal (items total + preliminary 8%)
And only then VAT 20%
Then total.

At the moment 20% calculates based on items subtotal and ignores the preliminary 8%.

Thanks for ideas or answers.
