Detailed Fields for TAX in income invoices

Hi first of all thanks for the great work you've done on this app.

A quick one, in the income session it would be good to have 3 fields when importing invoices to

1- Gross amount( or Subtotal before TAX)

2- Tax Deducted (usually 20%)

3- Total amount ( or After tax amount )( This is the amount paid into the bank account)

It's because I the UK for a self employed when I issue an invoice another business or company they have to deduct income TAX 20% tax from the invoice and pay the HMRC.

And I need to keep track of the 3 information( Total Gross, total TAX paid and Total payments after TAX)

Also invoices sent to private clients have no tax deduction

If not able to add this to Income session, please tell a way that I can keep track of this informations.
