Add new LIST partition based on passed id in stored proc?

Hi! Thank you for taking a look.
I have a table with LIST partitioning. We need to have each client in its own partition:

CREATE TABLE `mydb`.`test` (
`client_id` INT NOT NULL,
`client_name` VARCHAR(45) NULL,
PRIMARY KEY (`client_id`));

ALTER TABLE test PARTITION BY LIST (client_id)
(partition p100 values in (100),
partition p101 values in (101));


I am trying to create a stored procedure to be called when a new client is created:


DELIMITER $$
USE `mydb`$$
CREATE PROCEDURE `util_partioning_partition_new`(IN p_client_id INT)
BEGIN
DECLARE partition_name varchar(25);
select CONCAT('p', p_client_id) into partition_name;
ALTER TABLE test ADD PARTITION (PARTITION partition_name values in (p_client_id));
END$$

DELIMITER ;
;

and getting this error:
Apply changes to util_partioning_partition_new Error 1064: Constant, random or timezone-dependent expressions in (sub)partitioning function are not allowed near 'p_client_id));

PLEASE HELP! How do I pass client ID to the values in()?

Many thanks in advance,
