Multiple query matching for modalities within CCG for the DICOM worklist

The query matching for modalities in CCG is currently limited to one single value what limits the possibility of selecting more than one modality when this is set. As an example, some RIS are sending information for more than one modality within the same request as (MG +US). Currently we are not able to find for instance once of them like the MG since we are limited to only one value.
