Initially focus area select input when assigning devices in the new home dashboard devices view

I think the new workflow for finding unassigned devices is great. But I´ve seen and experience myself that the only thing I want to do here is assigning areas. So I have to click on "assign" and then again into the area select input. I think is would be great if the area select input was preselected/focused to have the following flow: user clicks on "assign", the dialog appears with area select input focussed and opened so the user can directly type the area.
