Rogerio,
You could use those stored values during data generation to reflect the values being currently used in production or development. If you go into the data pool and editing the entry for the People table shown in the example and then click on the drop down on any of the columns you have profiled like First Name you will get to a screen like below.
Then hit the lov button at the bottom of the screen and then select values from prod/dev. You should now be able to select one of the values you save during profiling. The advantage is that once you select any value the corresponding other table values you profiled like last name, lob etc are auto populated. This will keep your data referentially intact.
Thanks,
Anil
