Pattern for naming objects

It would be a handy feature to allow user to define patterns for default object names, eg. primary keys. Currently, PK is formed using pattern "{objectName}_pk". Such pattern could be defined by user, having access to variables like {objectName}, {objectNameSingular} (for objects named in plural form). For FK, source and destination object names could be accessible, so user can form default FK name as "FK_{sourceObjectName}_{destinationObjectName}". I'm aware, that this can be done via explicitly naming PKs and FKs, but such feature would be useful when model is big and many relations exist.
