What I mean is when you capture a planet can you decide not to start a colony on it. I have removed all population from a planet hoping I wouldn't have manage it but the next turn it is still under my control and the population has increased from 0 to 100.
My reason for this is on a large or huge map with war as the only option I will be trying to manage up to 20 or 30 weak planets that I don't want.
