fill cel with one of two puldown menu's

Hello to all of you, I’m new here and member of a dutch forum but clould not find the answer

I have a invove with;
NAME
COMPANY NAME
ADRESS LINE 1
ADRESS LINE 2

I use vertical search with a pulldown menu in “NAME” cel so the rest is filled automatically
Sometimes i dont know the name of my client
Now i want to fill the cels by searching vertical the “COMPANY NAME”

Is it posible to fill the 4 cells whit either pulldown “NAME” or pulldown “COMPANY NAME” ???
The 2 pulldown menu’s can be somewhere outsite the printed invoice area
