MySQL - Trigger for updating same table after insert

Question

Here's what I'm trying to do:

When there's a new INSERT into the table ACCOUNTS, I need to update the row in ACCOUNTS where pk = NEW.edit_on by setting status='E' to denote that the particular (old) account has been edited.

DELIMITER $$

DROP TRIGGER IF EXISTS `setEditStatus`$$
CREATE TRIGGER `setEditStatus` AFTER INSERT on ACCOUNTS
FOR EACH ROW BEGIN
    update ACCOUNTS set status='E' where ACCOUNTS.pk = NEW.edit_on ;
END$$

DELIMITER ;

The requirement is NOT that I manipulate the newly inserted column, but an already existing column with pk = NEW.edit_on

However, I can't update the same table: Can't update table ACCOUNTS ... already used by the statement that invoked this trigger

Please suggest a workaround

PS: I have already gone through Updating table in trigger after update on the same table, Insert into same table trigger mysql, Update with after insert trigger on same table and mysql trigger with insert and update after insert on table but they dont seem to answer my question.

Edit

ACCOUNTS Table:

CREATE TABLE  `ACCOUNTS` (
  `pk` bigint(10) unsigned NOT NULL AUTO_INCREMENT,
  `user_id` bigint(9) unsigned NOT NULL,
  `edit_on` bigint(10) unsigned DEFAULT NULL,
  `status` varchar(1) NOT NULL DEFAULT 'A',
  PRIMARY KEY (`pk`) USING BTREE) ENGINE=InnoDB AUTO_INCREMENT=2147483726 DEFAULT CHARSET=latin1

It seems that you can't do all this in a trigger. According to the documentation:

Within a stored function or trigger, it is not permitted to modify a table that is already being used (for reading or writing) by the statement that invoked the function or trigger.

According to this answer, it seems that you should:

create a stored procedure, that inserts into/Updates the target table, then updates the other row(s), all in a transaction.

With a stored proc you'll manually commit the changes (insert and update). I haven't done this in MySQL, but this post looks like a good example.
