The Preschedule step is used to modify blocks to their anticipated state at the start of the schedule.
Manual Preschedule
Blocks can be manually prescheduled by selecting them (either in the block tree on the left, or box-selected in the viewport) and clicking the flag 
icon in the toolbar.
To manually preschedule blocks:
Use the Visibility Mode button to toggle between viewing all blocks, or only the currently selected blocks in the tree.
Select blocks in the viewport.
Press the flag icon from the toolbar.
Set percentage remaining in the block.
Tick Remove Full Prescheduled Blocks.
Press OK.
Auto Preschedule
Blocks can be prescheduled from a starting surface via the Flag Auto Preschedule icon
. The starting surface must already be loaded into the Layers panel (bottom left).
Load a preschedule surface:
Locate the Layers panel in the bottom left of the screen.
Press the blue plus icon to import a new surface.
Navigate to the samples folder and import the preschedule surface.
Automatically preschedule blocks above the surface:
Press the Flag Auto Preschedule icon above the viewport.
In the Preschedule with Surface window:
choose the preschedule surface;
set the minimum and maximum thresholds (values outside of threshold will be rounded up or down).
Tick the records to be prescheduled.
4. Use the Legend button to see colors assigned by the remaining ratio.
