Of course, but why would you do that on a leaderboard of the highest payout posts (which is what the badly-named "Trending" represents)? Steemit.com can offer a different home page with whatever sort of filtering rules, and indeed I think the biggest problem with this platform is people can't filter and display what they want. You can't even look at one person's blog without seeing resteemed posts, nor can you look at posts with one main tag without seeing posts using the same tag as a secondary. The entire organization is terrible. But this has very little to do with Steemsports, which are not only games but also (sport-oriented) blog posts BTW, so it isn't even clear to me how that would be categorized if it were possible. Some other game posts are more clear though.
