Automated testing of Ionic built app with Appium?

Coming from native Android and previous use of MonkeyTalk for automated testing. Digging into Ionic and hybrid apps, Appium provides test automation for such apps. A key element of simplifying automation (in both Appium and MonkeyTalk) is use of the ‘content descriptor’ attribute of each screen element … easy to definitively address script processing to a known/specific displayed element.

Yes, it does appear that under certain circumstances the content descriptor attribute is inferred (based upon observation of the ‘ccoenraets’ conference tutorial). Has anyone looked at the ability to explicitly specify the content descriptor of each screen element? (note that a similar attribute exists for iOS platforms).

Thanks in advance,
