AGL Battery Rewards... Different peak for Import and Export

Any ideas on how to best setup pvoutput to cater for this? Technically you get a gift card and not a discount (FIT) on your bill for this period, but it would be cool to be able to see the benefit (basically it’s banded, i’d like to only show the value of what i’m actually exporting, it doesn’t need to be banded like the below)…

The problem is, if I want to be able to set this up, it uses a different peak time for imports (3-9pm) to exports (5-9pm)… Any ideas how to do this?

Over a 3mth period if you export between these, inclusive, you get a card:
(and so on, this is just a bit)

Amount exported Quarterly gift card amount
1 to 40 kWh $10
40.1 to 80 kWh $20
80.1 to 120 kWh $30
120.1 to 160 kWh $40
160.1 to 200 kWh $50
200.1 to 240 kWh $60
