When I look at a passage in Factbook, the Commentaries section allows me to Group by Denomination. Is there a way to create a Collection based on Denomination? Obviously, the data is there since it's available in Factbook, but I can't figure out how to access it when building a Collection. Can someone show me the syntax for this? If it's not available for end-users, I'll submit a feature request.
I've built Collections for commentary types (Application, Devotional, Exegetical, etc.) based on community tags, and they come in handy. I think having Collections based onf Denominations would also be useful. (I realize having too many of these can slow down Logos startup.)
