No this is not recent, it has been there since our very first release of the DDT.  Glad you found it though.

I use this import a lot, the only thing I notice is that it will create a new Database in the DDT, so I always copy the table to the proper database and delete the new created one.

I appologize, I totally missed this. When I originally imported my database I was sure I could only do the entire database.  Was this a recent addition? 

I guess I am somewhat confused by this post because you can import a single table at a time:

This is also covered in the documentation:

Databases -> Importing Databases -> Importing from SQL Server

It would save me a lot of time if I could have the ability to also import a single table at a time. We are in a transition stage where we are not using the toolkit to deploy structures yet but I am building all the relations etc... so I find myself having to manually duplicate all new tables which can lead to many typo's and incorrect setting.
