Micro OLED - How many can be addressed via I2C?

I am enjoying working with the SparkFun Micro OLED and my Teensy 3.6.

It seems as if the Micro OLED I2C addressing with the jumpers on-board only allow you to have 2 of these displays independently controlled over a single I2C connection. Is that true? I’d like to address up to 30 Micro OLED displays from a single Teensy 3.6 which is not a problem for I2C but seems to be a limitation on the Micro OLED board because of the two jumper positions. Any simple way around this?

Thanks!
