Adding additional selections in the overlay screen - Food Ordering App

For the browse menu is it possible to add a user selectable field in the overlay screen. The selectable field will also have a value which needs to be added to the price. E.g. a user must be able to upsize a burger (or additional toppings) and the value/s must be added to the total price.
Or can a “prompt” pop up happen (doing the same as afore mentioned) when the user click on the +add button, seeing that a menu item can be added to an order from different places.
