Lack of Componentization in GalCiv2

In Stardock Central, GalCiv2 had several components in the tree under it (Tutorials, Movies, Height Maps, etc.), which made subsequent installs faster and smaller because I didn't need to download the parts I didn't want (like the tutorials, for example). With Impulse, however, the games are all-or-nothing, and I'm forced to install all of GalCiv2 whether I want it or not. Please put back the sub-components.

If there's an option somewhere that I missed, please let me know and accept my apologies. I haven't found one for this so far, though...
