How to change the output_i2s2.cpp file to make it left-justified I2S

I am using a DAC that requires left-justified I2S format. Is it possible to modify the output_i2s2.cpp file.
I think I just need to change the data channel timing to be in sync with the LRCLK, but I'm not sure how to achieve this.

Thank you so much for your help! It seems like tweaking the register settings in AudioOutputI2S2::config_i2s(void) did the trick. I'll double-check with a logic analyzer to make sure everything's running smoothly.
