Can I add commands executed when you press the "Build Model" button?

I use Embedded coder to generate C-code and after code genereation I want to automatically: 1. Delete all the files (not folderes) in a folder containing my generated C-code 2. Unzip the zip-file genereated by "pack-n-go" to previous mentioned folder.

Would it be possible to make a tag in SVN to? To the step where you write the message and choose folder would be perfect!
