Hitpoint Placement by Tapping

I have to place a hitpoint at every downbeat in my song to create a tempo map. It’s not always obvious visually in the wave where exactly the downbeats are, so I have to play through the song and try to catch each downbeat, and sometimes it takes many tries to find the most likely spot to drop my hitpoint. Why can’t hitpoints be placed simply by tapping a key? Just like Tap Tempo, but each tap of the key drops a hitpoint, and it seems likely that you would only have to play through the entire song ONE time to get all your hits! For me, this feature would be a huge assist.
