Kill Switch update: We have temporarily disabled The Legion due to an issue that allows for infinite power spam. The Legion will be re-enabled once this issue is fixed.

Secondary button slot to killer interactions in Killer Control Mapping under Options

As survivor you have the "Pick up items/Interactions" and "Actions" fields in Survivor Controls. This allow you to map another button to one of these actions so you don't have the same button to two different actions like when a survivor is downed at an undropped pallet and you can drop the pallet or start healing him/her.

Here's the thing: for killer you only have the "Interactions/pick up survivor" field and that's it. When a survivor gets downed at, for example, a window you have to give your back to the window to pick up the survivor because otherwise you'll vault the window instead of picking up your victim since you get two interactions (vault and pick up) assigned to the same button.
