When will the option to report players for being elo-boosted become available? (Checklist included)

Too many times have I seen players in my games who are very explicitly elo boosted to the tier they are playing in. And it's not them just having "a bad game", it's consistent losses until a certain point where they previously played good, but suddenly started losing a marginal amount of games with their in-game performance being extremely underwhelming. Here is a checklist on how to spot an elo boosted player: Flash on different key? ✓ The most dead giveaway. Playing extremely well on specific champion(s) or role, then suddenly switching roles or champion and going on a massive loss streak? ✓ This means they paid the booster to play W/E they are good at, and then when they have completed their boost, they go back to their old ways. Severely different stats from previous games including CS, KP, KDA, ward placement and other gameplay factors? ✓ Playstyle completely changes E.G from passive-support player to a hard carry midlane main? ✓

And there are more ways to find out if someone is eloboosted. However, for those who suspect the player is boosted from the very moment they enter champion select and when they play throughout the game, the report button should solve that by notifying Riot about such suspicious behaviour.
