Preloading resources: Subsets, Many resources, CDN?

If found some interesting info here:

From what I understand you basically have to change the JS from:

psychoJS.start({
  expName,
  expInfo});

to:

psychoJS.start({
  expName,
  expInfo,
  resources: [
    // relative path to index.html
    { name: 'trialTypes_A.xls', path: 'trialTypes_A.xls' },
    // absolute path:
    { name: 'trialTypes_B.xls', path: 'http://a.website.org/a.path/trialTypes_B.xls' }
  ]
});

and then, your script will not load all resource files by default but instead only the ones that you specified. The question is now: how can I include this in my PsychoPy–>PsychoJS script? The builder always overrides changes in the PsychoJS script. But perhaps I can use the PsychoJS script made from the builder, make my changes there and upload it in a new project where I don’t use the builder?

Any thoughts anyone?

Thanks!
