Currently when comparing the contents of databases which contain singleton tables (no primary key single record) it is very time consuming to setup the compare. It would be very helpful if an option existed to change the default behavior for tables with no primary key. For most of my use cases I need to spend 10-20 minutes selecting every non-lob column as a key for these tables. A checkbox in the options screen could exist called something like "Automatically Map All Non-Lob Columns when No Primary Key Exists"
