There is no such compulsion. Donβt worry and go to your appointment. If you have answered all the questions correctly your applications will automatically get linked.
Your application will mention her passport number and hers will mention yours. A GWF is not the only thing to establish a link. If it was so important they would have listed it as a separate question. They donβt expect everyone to automatically know they have to put each otherβs GWF numbers in notes.
When they take your documents they will link your applications and your documents will go to the decision center in 1 bag.
