Sentinel: Filter Incidents by responsible user

How can I filter incidents by responsible user?

Currently, there is no easy way to group by person responsible in the Sentinel Control Center. This can only performed via SQL command.

select users.name, incidents.*
from incidents, associations, users
where associations.table1='INCIDENTS' and associations.table2='USERS'
and incidents.inc_id = associations.id1
and users.usr_id=associations.id2
order by users.name
