Workload Balancer Filter Enhancement

[#1]

The current 'Filter' in the Workload Balancer has limitation for the following functionalities whereby these are available in other objects type such as Projects, Tasks, and Requests.

1. Select the Filter condition for "Include if all are true" or "Include if any are true". (Currently defaulted to ‘Include if all are true’ and not editable)
2. Select 'Add Filter Groups' for filter operators 'AND' or 'OR'.
3. Switch to Text Mode interface.

It would be great if these functionalities to be made available in the Workload Balancer Filter to allow Resource managers to build complex filters for accurate resourcing.
