Splitting Duplicates in a Subreport - MSSQL / Crystal Reports

I would like to generate a PIS and COFINS tax forecast report, which is calculated based on a CFOP code of the notes issued in a given period, but would like to separate this information in "blocks" / p>

I expect the result this way:

+--------------------------------------------------------------+
|                           CRÉDITO                            |
+---------+----------------+--------------+---------+----------+
|  CFOP   |    Descrição   |  Valor Base  |   PIS   |   COFINS |
+---------+----------------+--------------+---------+----------+


+--------------------------------------------------------------+
|                      DÉBITO - Cumulativo                     |
+---------+----------------+--------------+---------+----------+
|  CFOP   |    Descrição   |  Valor Base  |   PIS   |   COFINS |
+---------+----------------+--------------+---------+----------+

+--------------------------------------------------------------+
|                    DÉBITO - Não-Cumulativo                   |
+---------+----------------+--------------+---------+----------+
|  CFOP   |    Descrição   |  Valor Base  |   PIS   |   COFINS |
+---------+----------------+--------------+---------+----------+

I believe that for this I will need to use SubReports in Crystal Reports, but I can not think of how to organize the groups in the report and subreports. Remember that all data will be based on the same period that will be passed as a parameter.

The SQL used is basically the same in all reports, changing only the percentage value for tax basis depending on CFOP.

Here is the example SQL that returns the issued NFs (which will generate the debit "blocks"):

DECLARE @PIS decimal(5,4) = 0.0165;
DECLARE @COFINS decimal(5,4) = 0.076;
DECLARE @PIS_I decimal(5,4) = 0.0065;
DECLARE @COFINS_I decimal(5,4) = 0.03;

                    WHEN Base = 'A' THEN 'Imune' 
                    WHEN Base = 'B' THEN 'Deferido'
                    WHEN BASE = 'C' THEN 'Tributado'
                    ELSE '' END)
    ,[Valor Base]
    ,'PIS' = CASE 
                WHEN Base = 'A' THEN [Valor Base]*@PIS_I
                ELSE [Valor Base]*@PIS END
    ,'COFINS' = CASE 
                WHEN Base = 'A' THEN [Valor Base]*@COFINS_I
                ELSE [Valor Base]*@COFINS END

                    ELSE SUBSTRING(REPLACE(REPLACE(NotasFiscais.cfop1,' ',''),'.',''),5,1)
