IPM Advanced Predictions - Input Drivers

Has anyone used historical revenue pipeline as an input driver for revenue forecasting in IPM Advanced Predictions? Trying to understand how this should be configured in the application.

We’re currently testing using new members in the Account dimension, e.g. Pipeline_Snapshot. However, there are 2 dates to consider, the snapshot date and the revenue period date. The snapshot date represents what the open opportunities looked like on e.g. January 1st 2025 vs April 1st 2025 etc. and the revenue period represents what portion of the opportunity amount was allocated to each period.

How should this be configured in the application to train the model on the conversion of the opportunity pipeline into actual revenue?
