I had a kerbal go down to the Mun and collect various science data. All of it is now transmitted, except for three surface samples, two of which have been processed. The third can't be processed because there isn't enough data capacity. In theory I could just make room by removing the processed experiments and putting them in a command pod, for instance. Unfortunately I can't figure out how to do this, because there is only the option to take all data, not some of it. All I can do is transmit one of them, which is suboptimal. I'd really rather take them back to Kerbin, and I have a little spacecraft ready to do just that (I sent it on the same rocket as the lab itself). Is it possible to remove only the processed experiments without transmitting them, so I can process the unprocessed ones?
