All Transactions Report - add transaction type column

I generated an All Transaction Report (to try and figure out realised gains) for a period (financial year) and there is no column for Transaction Type (ie Sell or Buy). I can see that the quantity column has positive and negative numbers presumably to indicate Buys (incoming...add) and negative numbers presumably to indicate Sells (outgoing .... subtract).

Would be beneficial to have a column which says "Buy"/"Sell" to indicate the transaction type. This would also make it much easier to generate a Pivot table out of it in excel.
