In Odoo v16, the Down Payment features is a great though there are 2 aspects I would like to improve --

1] On the second invoice the total cost minus the down payment are both reflected. The customer knows how much they owed and how much they've paid so far. However, besides the line item saying the % there is no reference of the total balance on the first invoice to indicate the total that the Down Payment is going towards. In the accounting platforms I've encountered there is usually the ability to display the amount due now and the amount due later. I could manually enter it into the Down Payment invoice but I was wondering if there is a setting that I'm overlooking that would display this information automatically?

2] Another feature I'm used to seeing is a reference on the second invoice to the first invoice #. For example, Invoice #200 will reference that the Down Payment was from Invoice #172, making it easy for the customer to refer to the previous invoice in their records if they needed to. Any ideas for how I might add this?
