Ahg! No. :-)

No, unfortunately generating the migration again will regenerate everything. 
After the initial migration, you'll need to manually write a new migration 
class, or do generate and manually remove the duplicate stuff - whichever is 
less work in your situation.

Basically create a second model class and increment the number from "0" (which 
is what your first migration class should have) to "1", eg MyModel1.java

Basically, Migrations will check to see if 0 was run, then it will look for the 
next class (by number) and then execute that one. And on and on and on.
