Would it be possible to add (at the project level properties) the ability to automatically add new columns when creating a new table?

The following columns woul be usefull:

1. Int Identity Primary key (name PK, or ID, with or without %TablePrefix%_)
2. Timestamp (name TSTMP,  with or without %TablePrefix%_)
3. UniqueIdentifier default NewId() (name UID, with or without %TablePrefix%_)

thanks in advance
