Probably a stupid question…

My wife and I are reading the same book. I purchased two copies, one for my account and one for hers.

Once we’re done reading it, we’d like to be able to share the highlights with each other. Ideally if I highlighted it, it shows up a one color, If she highlighted it - a different color, and a third color if we both did.

That way we can review it, after individually reading and essentially compare notes.

Is this possible?
