SDA electricity generation investment

We are looking at the SDA v2.2 tool for investments in electricity generation assets. Is it a requirement to include both Scope 1 and 2 base year emissions as input? As the cell F18 updates when information is entered to just say “tCO2e (S1 intensity: X tCO2/MWh)” - this refers only to scope 1 and not scope 1 and 2?
Furthermore, is it acceptable to just use scope 1 if scope 2 is less than 5% of the total scope 1 and 2 emissions?
