What we want is to change the item in the base image combo. The target image is still based on the base image the user selected plus delta.
We have the strict definition for the predefined base images. For instance, sato includes 300 recipes.
An image including 299 recipes is not called sato but your own image (say, sato-minus)

The reason why we do that is because for templates, we will remember the item in the image combo as the base image in some bb file, and we also remember what we selected for the recipes and the packages. However, the base image covers all of them by default and because of that, bitbake can't recognize the delta and will include all (300 recipes), which causes the wrong behavior.
