Using toolkit to change navision objects

Hello,

I would like to know if there is a possibility to do massive code modification in the toolkit and then export the objects again to navision.

Example:

If I have to implement the CaptionClass to the field posting date, I would prefer do that change on the very hard way, and then import the objects to the database.

If I can't do this I would have to change the Caption Class property, in every object where this field is inserted, with my one fingers.

Please heeeeeeeeeeeeeeeeelp
