Project Forecast FBDI Load - Periodic vs Line "line types"

Summary:

When loading a Project Forecast for a new project, all I want to do, is to load the forecast amounts, in the periods I specify and NOT have Oracle spread the forecast values.

We are doing mass forecast loads, but these forecasts are continually adjusted manually by the project managers via the Oracle UI online, so they may move the forecasted amounts from one period to another, but they are unable to do so, because forecasts loaded using PERIODIC do not allow this.

As an example, for the below project, I just want to load amounts for two tasks, one of the tasks having amounts in 2 periods. I have tried numerous iterations and combinations, but none satisfy my simple needs.
