An update on this:
We have now a utility inside Collect Earth (last version 1.5.7 ) that helps you in the process of chopping up a big CSV files into smaller ones!!
It gives you the possiblity of randomizing the plots and also of dividing them using the values of one of the columns as the pivot. This is very useful if you want to divide the files into region/countries/etc...
Go to Tools->Utilities->Divide large CSV plot files

You can choose the number of files that you want to split the file into. If the order of the plots should be randomized so that interpreters get plots all over your area of interest, and, IF YOU ARE USING A CSV FOR THE SURVEY THAT IS LOADED then you can also choose one of the columns to generate strata-based sampling files.

In this example we are "chopping" the CSV with plots from Uruguay. We specify that we want the order randomized and that it should be divided into THREE files. Note that we also say that we want to "split files by strata" using the Cuenca column of the CSV.
This means that there will be three randomized files per strata! The resulting folder output will be divided into a folder with the plots NOT RANDOMIZED and another one with the same plots in a random order!!!

So if we had chosen the option to not Split the files by strata "DO NOT STRATIFY" then the result would have been :
