Flowdock integration: custom tags

Hi,

I would like to be able to tag messages in flowdock with the @team tag, so everybody receives an highlighted notification when something goes wrong on the server.

The actual parameters only accepts keyword tags (level, version, hash) and the notif is easily forgotten if you have several services integrated with flowdock.

results in
#error #none tags in flowdock

Or maybe there is a better way?

Thanks,

Aloïs
