Revit Need to add text to families

I need to add a text added to a filler family so that the number shows up on the elevation automatically. I also need a video (tutorial) showing how this was completed and how the same method can be used on other components. The product number that needs to be shown, should be movable and should update to a different product number when the size is changed. See attached files for reference. Revit file is included as well.
