The Attribute Assistant add-in can help you automate that. I guess it depends on how often you are going to be doing this and how many points (I am assuming you are creating address points.) you will be creating. If it is a lot of points it may be worth the time to figure out how the Attribute Assistant add-in works. I use it all the time to make data entry easier. Once you figure it out you start seeing other ways to use it.
The Attribute Assistant comes with most of the map templates for the Local Government Information Model. Try the Address Data Management map template. That map is intended to be used for new development and new addresses. The idea is you create a road centerline enter the ranges for that segment and then start creating site address points. The add-in fills in the house number and the street name and then concatenates them into a full address field.
For your needs I think you could use the GENERATE_ID method - setting the low address in the GENERATEID table and the increment value, then in the DynamicValue table create a line for your house number field and use the GENERATE_ID for the value method.
