Allergy Pop up

Hi Team, 

Noticed more and more restaurants are asking if you have any allergies and it shows on the receipt no allergy. I have got my staff to ask which is one great step in helping with food allergies but is there a way the system can pop up with a pre order question, IE Do you have any allergies, YES, NO? 

I know I use this system for Café and shop so not needed in the shop so would need to be optional.
