EXTI Level-sensitive interrupt

How can I configure the EXTI_Trigger to be level sensitive interrupt. By using EXTI_Trigger_Falling I can configure it to be edge sensitive but I need it to be level sensitive.

stm32f10x_exti.h specifies different options:

typedef enum
{
  EXTI_Trigger_Rising = 0x08,
  EXTI_Trigger_Falling = 0x0C, 
  EXTI_Trigger_Rising_Falling = 0x10
}EXTITrigger_TypeDef;

But there is no option for Level-sensitive configuration.
