James Lapine follow up to Putting it together?

Has anyone heard if James Lapine, is actually working on a followup to Putting it Together? One that discusses Into The Woods and Passion. I swear when Putting It Together I had read that he and Sondheim had recorded interviews/discussions on Into the Woods and Passion, for future publications and archives. But I've been searching the internet today and can't find anything. Has anyone heard anything of a similar nature. I would love a follow up.

On the Giants in the Sky podcast some years back he did indicate he was going to do an ITW book

I know around the time of the book, he was working on a screenplay again (anyone else remembering Jake Gyllenhaal wanting to make it?). Shame that died. Probably because streamers turned against making musical adaptations.
