I created a metadata model sometime back with some tables. Now one of tables included in the metadata model has a new column. what would be the process to include that newly added column to my metadata model?

I am not able to find any easy way to do this,except to delete the table, re-import it, and then repeat all the steps I did before like add to business model, relationship and then finally view.

Can some one please suggest if there is a way to update the existing tables so that they take up the newly added columns?
