Asset category change using NBV

Summary:

Content (required):

For our Asset Category Key Flexfield, we are using 3 segments: Major, Minor, and a third "Entity" that is the same as the GL balancing segment in order to easily identify asset Organization ownership and create accounting for entities.

When transferring an asset from 1 entity to another, we also will need to change the Asset Category combination to change Entity A to Entity B. The journal entries being created are crediting the entire original asset cost out of the original Asset Category combination and placing the entire cost amount into the new Asset Category combination. The business wants only the net book value amount moved, not the entire cost amount, so is it possible to account only NBV amounts via SLA rules?
