Suggestion - starbase debris symbol

Hi,

I've just been waging a perfectly successful war of squirrel genocide but stupidly left some of my hinterland exposed and lost half a dozen starbases. 

Replacing them is trivial but remembering which ones and exactly where a real pain. So I wondered if we could have a debris symbol both for ones we destroy and our own. Or - presumably simpler to code - whether the game could create a colour coded rally point each time a starbase - friendly or enemy - is destroyed which we could then either delete or act on.

Cheers,

Jon
