I have looked all around, but is there no comfy way to tag a lot of addresses in JOSM to existing buildings? AdressInterpolation obviously doesn’t suit the task and BuildingTools sounds promising, but the auto-tagging seems to work for new buildings only.
My current mode of operation is to create a phony building with all the tags for a street but the house number. Then I can copy these tags and paste them onto all buildings for a street via ctrl+shift+v. I need to tag house numbers manually and while JOSM auto-suggests the tag name, typing each number is still cumbersome.
Can anyone share a plugin or easier approach to this task? I welcome every suggestion.
