How to modify my.ini parameters of an Amazon RDS instance

Question

While launching a MySQL 5.5 RDS instance, Amazon uses a default parameter group to configure the my.ini parameters, but the console doesn't allow me to modify them. How can I achieve this? (e.g. setting the storage engine to MyISAM by default or setting character set ...)
