Can I generate BOM report separate by book

My project consist of two books name as Option 1 and Option 2.

I separate book because I want to create project two configuration(option) by option 2 has motor but option 1 is not.

This is my problem when I generate BOM report. Report is not separate components by book but it sum all components in project.

How do I generate BOM separate by book?

Thanks.
