about shift hotkey

Hello everyone

When playing voobly I used the ctrl key to select multiple villagers in different positions, and holding this key pressed the button for the number I wanted to assign to this group, and the control group was assigned.
Here in DE I have to use the shift key for the moment to select multiple villagers, and then switch to control to assign them the control group I want.
My question is whether this shift key can be changed for this specific function?

Thank you so much
