Save GPIO state on flash/eeprom

Hello!
I use EspEasy mega-20180130, i would save the gpio state, ex. every minute, in an .txt file, when esp boot (if occur a power outage or reboot) must read this .txt file and set the GPIO variable according to the last save.
How i can do that?
thanks

Currently no but it's planned to have external EEPROM support.

For me .... to let relay's controlling pumps survive their activity despite all watchdog reboots
I store GPIO states controlling a relay, in a dummy task.
With a Rule:
"On System#Boot do"
I restore the last known GPIO state
This works for a hot-boot, NOT a power outage.

For now i've solved with an UPS to avoid any power outage...
hope that this features (persistant relay mode in case of power outage) will be arrive soon as possible.
Thanks
