If I follow correctly, an idea topic which closely parallels what you’re after has already been set up for this. Difference being, instead of being based on a selection of tags and/or authors, it appears that you’re after all posts being included by default in the recap newsletter / digest. I presume building what’s mentioned below would by default include the option for what you’re after. You’re more than welcome to add your vote
Otherwise, and as we’re unsure if such a thing will ever be built into the platform, @Cathy_Sarisky has queried if people would be interested in paying for this functionality to be built. Feel free to add your two cents if you’d like.
