[Observium] Change severity on alarms

Hi

I was wondering if there are any ways of creating other seventies than Critical when creating alarm checkers?

For example I would like to have severity Informational and maybe some others. Also I would like to have the posibility to only send Critical events to all recievers of the alarms and Informational to the responsible group for specific alarms.

Is this possible? If so how do I do it? If it's not possible now, can it be implemented?
