Can someone tell me how to add a commentary to my bible reading plan?
The only way to have multiple books in a reading plan is to create a Custom Reading Plan and add each book to specific sessions.
Assuming this is an existing plan that you are partway through, that could be a challenge
One other option is set up a layout for your reading plan, add a commentary to it and link it to your Bible. That way it would always be at the correct place.
It doesn't do exactly what you are asking for but it gets close.
Would that work for you at all?
yes. Thank you
