I've worked in several municipalities, and almost every data extract or spreadsheet I've seen has the house number and the street name broken into separate fields, eg:
The input parameters for geocoding in Desktop and Pro require this as a single field. The user has to go through the extra step of concatenating these fields, prior to geocoding. This is trivial for an advanced user, but it can be a dead-end for less experienced users.
I've taught a lot of GIS trainings, and this is a real problem for a lot of people.
I'd like to see the interface that expanded to include the option of separate house number and street name fields.
(not sure how the interface would look - this is just an example.)
