Solar Max Stepped Pricing

I am wondering if there is any way to set up the pricing etc. for this scenario.

My supplier will credit me for “…the first 10kWh average daily export” at 8c per kWh after that the credit reverts to 1.5c per kWh.

This is the definition of Solar Max Stepped Pricing as per disclosure statement…
Solar Max Stepped Pricing:

The higher solar buy back rate (feed-in-tariff) applies for the first 10 kWh average solar export per day. The daily export is averaged by dividing the total solar export by the number of days in each billing period. The higher retail solar buy back rate applies for the first 10 kWh average solar export per day after which, our standard solar buy back rate will apply.

Any help would be appreciated.

Cheers,
Colin
