Hi Gary, 

Thank you for reaching out. Please take a quick look at our Logical Modeling article for a brief overview of what is available currently. We also have added a logical column to the Database Documentation feature, which was added in the last release. (Please see screenshot below). Lastly, you can switch view modes on your models to showcase different views (logical, keys, table name only, etc. by clicking the View Mode button in the top middle menu. 

I hope I understood your inquiry, but please let me know if not. Thank you!
