Quick question - how to keep track of enemy base location once scouted?

Details here: So, in Supcom, once you had scouted your opponents' base, while the units would vanish (naturally), the structures would still have darkened strat. icons hovering over them. In PA, at least to the best of my knowledge, this does not happen. How can I change this? Is there a mod for this, or stock functionality? I ask because I play on a bit of a toaster and while zoomed out, sometimes those silhouetted structures are a bit hard to spot.

Click on top left player icons.

Thanks! ^_^

Also, the camera position recall hotkeys are very useful. Shift-# will save your current camera position, alt-# will snap your view back to it. So, shift-1 over your base, shift-2 over the enemy
