Different views inside a document set

I have a site which has a large list of Document Sets, one for each customer.  These document sets are grouped by their country.  However, when opening the document set, the contents are also grouped by country, because by default, a document set uses the same view, and it's not smart enough to realise the grouping is for the document set, not the contents.

Easy solution I've just discovered (thanks to this blog post) -

1. Create a new view, based on the original view, but without the Grouping
2. Open the Library Settings, and select the Data Set from under Content Types
3. Select Document Set Settings.
4. Scroll down until you find the Welcome Page View setting - you can change the view here.
