STM32F746 Discovery VBAT

Why the big featured STM32F746 Discovery Lacks in External VBAT pins 

This makes the board completely unusable for backup test and RTC time keep up

 

The designer had concentrated only on big features like LCD, SDRAM, FLASH and others but simply forgot about external VBAT for testing its Backup facility

 

Is there any other way to make the VBAT external so that we can connect and run RTC even there is not main power
