Hi Edgar,
Yes, it is possible, however note that you can only have one geometry field per feature layer. Therefore you can only have one geopoint question that is stored as the actual geometry for that feature in that layer, but you can create all the other geopoint questions in the same layer as null esri field type, and then pull out the x and y using a calculation to store the values.
