Hi,

yes, for new objects you can specify Default Values (Expert mode must be enabled). Click Settings | Default Values and in section Entities click default value next to Name, press F2 and enter there value T\<%UniqueNumber%\>. Then RESTART Toad Data Modeler and try to add new entity to your model.

Regards,

Vaclav
