event switcher: match any value in Data Provider

Hi,
How can I set an event in event switcher that matches any value other than one defined value? I thought with 'event_name:/[a-z]+/, * matches any value.' but I must have that wrong.
​
I have tried
​
Data Provide {data:group}
Events
OFFICE
OTHER:/[a-z]+/, *
​
but I must have that wrong.
​
I want to take a specific action in the case of {data:group} = OFFICE but a different action in all other cases.
I have a work around but want to understand this.
​
Regards
​
