How do I use MySQL Master/Slave replication on RDS for multiple instances?

To use MySQL Master/Slave replication on a standard MySQL database I use the following code:

CHANGE MASTER TO MASTER_HOST='123.123.12.12',
MASTER_USER='user',
MASTER_PORT=3306,
MASTER_PASSWORD='123456',
MASTER_LOG_FILE='binlog.000004',
MASTER_LOG_POS=7947 FOR CHANNEL '123.123.12.12';

START SLAVE FOR CHANNEL '123.123.12.12';

This code does not work on AWS RDS because there is no SUPER privilegies for any user we can access:

Error: Error Code: 1227. Access denied; you need (at least one of) the SUPER or REPLICATION_SLAVE_ADMIN privilege(s) for this operation

Therefore, we need to use the stored procedures from aws mysql-stored-proc-replicating documentation. I then I start the replication using the following command:

CALL mysql.rds_set_external_master (
  host_name
  , host_port
  , replication_user_name
  , replication_user_password
  , mysql_binary_log_file_name
  , mysql_binary_log_file_location
  , ssl_encryption
);

CALL mysql.rds_start_replication;

It works fine! But the problem is I wanted to do this replication from RDS to multiple different Windows Server (with MySQL installed). To do that I would need to use FOR CHANNEL '123.123.12.12';.

1. Is there a way I access SUPER PRIVILEGIES in RDS to run the standard CHANGE MASTER TO MASTER_HOST instead of the procedure?
2. If not, is there another way to replicate from RDS to a MySQL installed in a Windows Server? Considering multiples Windows Server.
