Yes there is. After selecting the I2C in the CubeMx, Keep pressing ctrl key and select that pin. CubeMx will show you the alternative for that. Just drag and drop the selection to the new pin.

@monjiro make sure you select the right pins for the i2c. Check the schematics of the board to see which pins you need to connect to. I am guessing that you have connected to the pins on the top right (scl and sda). When you enable i2c1 in cubemx, by default it will not configure these pins. You have to change the pin manually.
all SSD1306 have the same I2C address. So if u do connect them to the same I2C, they will show the same data. If you can somehow modify the address, then u can control them individually
yes, but follow this: -open "ssd1306.c" -in line 194 change "SSD1306_WRITECOMMAND(0x3F);" to "SSD1306_WRITECOMMAND(0x1F);" -in line 203 change "SSD1306_WRITECOMMAND(0x12);" to "SSD1306_WRITECOMMAND(0x02);" if you do that, you are sending , with I2C protocol the especific command to OLED 0.91(128x32) to change 128x64 to 128x32. Otherwise it will never work.
