Not sure you can do keybinds, I'll post a img with my pro mspaint skills.

Step 1. you can Left click, shift-left click, do whatever you want with your mouse and it'll be over in the right side panel, then choose the Target/Action target group and what you want them to do, create a Key map with the ingame bind you want the click to send to the alts.
EDIT: What I've done is create a key map for drinking and have it Target=self in the Key map, then in the clickbar use the target you want to make drink
