Keep "Recommended" category clean from already in library games

It has been bugging me for a long while, whenever I jump into that category I mainly see Humble Choice games (which I already own) or similar cases where I own the game in question. From the picture I linked, the first few items in the recommended section are 3 games that I own, 1 that I'm hosting (literally the same GA I'm doing) and the other 4 are not in library. That might look ok at a first glance, but there are worst cases where my whole page is filled with stuff I own.

Is there not a way to implement a case to remove from the list those games owned by the person checking this category? It seems like the page can tell if I own it on the GA page, would it be harder to implement on this part? Sometimes I forget about the stuff I bought/gotten from bundles so it would be helpful to not waste time in opening the GAs to see that I can't join. Thanks!
