Two situations I encounter often:
1. Enemies have sniper/spotter. I want to avoid reaction firing because shooting one random enemy isn't worth having 10 enemies grenade me from across the map.
2. I want to capture a specific target. I want to avoid reaction firing and not kill them
In either of these situations I need to clear everyone's TUs to avoid the unwanted reaction firing. Which gets laborious when I'm skipping 10-20 turns waiting for an enemy to show up. With 14 soldiers that means repeating tab+delete a minimum of 140 times per mission. A hotkey to remove TUs for the whole group would be helpful, I'd suggest shift+delete as the default.
