We Need More Search Preferences

Honestly, I see a lot of posts about people dash-boarding to get out of lobbies. Instead of this, why can’t we have a search filter added, so if we don’t really like Overgrowth, for example, we can choose to not be matched into overgrowth lobbies.
There is very few downsides to this, for example, instead of losing teammates at the start of games because they don’t like that map/gametype, now we are paired with people who want to play it.
