A dirty workaround would be to add the same mapservice 10 times to your webmap, with only one sublayer checked per added mapservice, and then rename the service accordingly. I wish there was a better fix for it, but that's the only how I can make the individual sublayers available for the simple app hosted on AGOL.
Cheers!
