Query 2 record types in gridField()

My interface is now using a record type (data source is a process report) to show a list of cases info, now I want to add into this interface 2 additional columns, but the data for these 2 columns is in another record type, and the common field to get the right data is "caseID". 

 Is there any possible way to query the data from the other record type back to this interface? I tried but couldn't point to the exact case ID...

a!boxLayout(
    label: "My Pending Tasks",
    contents: {
      a!gridField(
        label: "",
        labelPosition: "ABOVE",
        data: 'recordType!Cases',
        pageSize: local!selectedPageSize,
        columns: {
          a!gridColumn(
            label: "Case Id",
            sortField: 'recordType!Cases.fields.caseId',
            value: a!richTextDisplayField(
              value: a!richTextItem(
                text: if(
                  rule!AAA_CMN_IsBlank(
                    fv!row['recordType!Cases.fields.caseId']
                  ),
                  "-",
                  fv!row['recordType!Cases.fields.caseId']
                )
                ),
                a!gridColumn(
            label: "Created Date",
            sortField: 'recordType!Cases.fields.createdDate',
            value: a!richTextDisplayField(
              value: a!richTextItem(
                text: if(
                  rule!AAA_CMN_IsBlank(
                    fv!row['recordType!Cases.fields.createdDate']
                  ),
                  "-",
                  fv!row['recordType!Cases.fields.createdDate']
                )
                ),a!gridColumn(
            label: "Updated Date",
            sortField: 'recordType!Cases.fields.updatedDate',
            value: a!richTextDisplayField(
              value: a!richTextItem(
                text: if(
                  rule!AAA_CMN_IsBlank(
                    fv!row['recordType!Cases.fields.updatedDate']
                  ),
                  "-",
                  fv!row['recordType!Cases.fields.updatedDate']
                )
                ),
                 a!gridColumn(
            label: "Case Owner",
            value: rule!AAA_CMN_General_queryRecordDataHelper(
              recordType: 'recordType!Cases Information',
              filters: a!queryFilter(
                field: 'recordType!Cases Information.fields.caseId',
                operator: "=",
                value: fv!row['recordType!Cases.fields.caseId),
                pagingInfo: a!pagingInfo(1,1),
                fields:'recordType!Cases Information.fields.caseOwner)
            )
                )}
