Using GPIO pins for additional I2C ports

Has anyone come up with a way to use GPIO ports as I2C? My current app uses an external I2C mux to make three I2C channels. I would like to replace this HW with independent I2C output from the STM8. So I would have three I2C master addresses on the MCU.

 

Thanks
