Preloadfile use in CSV files?

I'm wondering it it will be possible to use the new preloadfile command within a CSV file?

I'm anticipating it will improve the sync consistency.

For my latest test using 3.1.73 I'm seeing:
Minimum time to play: 274mS
Maximum to to play: 334.8mS
Average time to play: 299.1mS
Out of the 50 samples 92% of the time the time to play is greater than 284mS and less than 324mS.
So around 90% of the time the sync start across multiple players would be around 1 frame of 40mS
Audio wise this means that around 90% of the time the sync start is like having speakers 13.2m or 43ft apart.

It would be great to have sync within say 10mS or 1/4 of a frame.....

For the tests I had a 40MB TS file that plays when a GPIO button is pushed. While not playing the video
a black jpeg image is displayed, both files and the videomode are the same resolution. I measure the time from when the button is pushed to when the first video frame appears at the output.
