Enhanced Alert Filtering Options for Alert Widget

Currently the filter setup in the Alert Widget allows us to select which groups, devices/services, data sources, instances and datapoints, etc.  The datasource, instance, datapoints are applied to all of the groups and devices.

What we need is the ability to specify the datasource, instance and datapoints per group, for example, we need to be able to do the following in one Alert Widget:

Groups               Devices/Services        DataSource     Instances     DataPoints               

Networks UK       *                                *                        *                  *  
Networks DE       *                                Ping                  *                  *
Networks ZA       *                                Ping                  *                  PingLoss|Ping RTT
