GST Column in Expenses and Invoices

Hi There,

As someone who works with international clients - and, like a lot of us, buys stuff/things/services online - it would be very handy to have a column (with a checkbox!) indicating whether

1) GST has been charged on an invoice; and

2) GST has been included in the expense claim.

Priority for me would be a column in the expenses view with ability to bulk edit.

Thanks!
