I have successfully deployed the structures to the server.  Then I went back and made some table changes and deployed once again and everything works as expected.

Looking forward I see a deployment problem in my environment, in that many of my customers have multiple companies.  Each company has a separate database with unique database names but the table structures are the same, so I will need to run the deployment for each database. 

I can't seem to find any documentation on how to deploy my package to alternate database names.  It always uses the database name I used in the DDT.

Is this possible?
