Please add Audi AG offices
Currently, you can't select office buildings for Audi AG. Only factory buildings are available, which isn't suitable for many buildings.

We don't have a category for building=office, but we do have a category for office=*
https://github.com/osmlab/name-suggestion-index/tree/main/data/brands/office
So it could go in one of these files, or we could make a file for whatever kind of office it might be.

We mostly only add items for things that there are a lot of - for example 50 offices that should be tagged consistently.
