Can we have control on the precision of the coordinates when importing a FBX

We are currently searching for a solution to manage the precision of the coordinates of the JSON file.

Actually, the size of the JSON linked with a model is strongly related to the number of characters inside this JSON file. We can reduce significantly the size of a JSON file by reducing the precision of the coordinates like this:

(-0.345678, 1.234567, -0.987654) —> (-0.35, 1.23, -0.99)

This will reduce the size of our model a lot, and so the loading time.

Is there a way to manage that with PlayCanvas. I want to avoid parsing and editing my JSON files each time I upload them?

Side question from a curiosity standpoint: How big a difference is there are after gzipped compression?
