Kerbal Space Program

While there's only a single time where you would want to be selective about what you transfer from one container to another it is the time where you actually need that control: the lab.

I have a lab around the Mun and I have a large amount of experiments on it that I brougth up from the surface but some of it was already recovered in previous flights and some of it was not but was easily re-obtainable and therefore already fed to the lab.
So now I have a large amount of experiments in one container on that station with the lab and some of it is not useful for the lab and should just be send back to Kerbin for recovery while some is useful for the lab but is not useful nor intended for recovery and I have absolutely no way of seperating them since they're stuck in the same container.

What the game should offer is a button when reviewing science that allows transfering just that one experiment instead of limiting you to only be able to transfer the whole container's content at once.
