I guess you mean that your wife has same application number and different UCI. From my point of view, there is no need to do it through separate webforms. I already did it in one webform request for all two days backJust got back from my upfront medical exam.
Uploaded my e-medical forms for myself, my wife and my daughter through single webform update.
Fingers crossed it's accepted in January and COPR coming in March/April.
Does anyone know if i should upload a separate WebForm for my wife? ( She is my dependant but has separate Application Number, UCI is same. Daughter is 4y old, so she doesn't have an Application Number separately ).
