Here's another scenario that would benefit from being able to apply a part payment to specific invoice lines:
A two-line invoice includes a hire fee (income) amount and a refundable security/booking deposit amount (liability).
The deposit amount only is paid a few months early to secure a booking.
Xero apportions a part payment across all invoice lines which requires some manual journal jiggery-pokery at period end to put the full amount of the deposit into the liability account.
