Per line item expense categorisation

If a receipt has multiple items that fall under different categories, you can split them line by line.

In the expense detail view:

1. Tick Per line items?
2. For each row, set the item description, quantity, price, category, and tax rate
3. Mark GST included? if the row already includes GST
4. The total at the bottom updates automatically
5. Save

This is useful for trade receipts (parts, tools, consumables coded separately), or shopping receipts with both business and personal items.
