Sorry it's not that simple. You were approved as RVD, therefor we'll allow you to drop him, but in accordance with our new policy added several weeks ago. You will be frozen unable to pick up anyone else in his place so that you'll be more apt to keep whoever you pick up once the period of one week passes.
Once the week is up you can go for whoever you want just make sure they're who you want, will be active as, and will stick as.
