DIX9211: DIT Block block start sync

Tool/software:

Hi,

I need a reliable way to synchronize I2S audio data to the start of a block on the output.
Is the DIX9211 capable of either outputting or accepting a block start signal for the DIT?

Looking at the datasheet I can't see a way to do so, but I might be mistaken.

The DIX4192 seems to have the BLS pin that would do the job, but this chip is significantly more expensive for my application.

Thanks
