Google Cloud Test Lab

Yesterday, at Google I/O 2015, Cloud Test Lab was announced. One of its promoted features is: "you can run all of your tests across all devices, all at the same time--giving you access to massively parallel testing, bringing you deep and scaled insight".
Wow, that's pretty much the same I described in my previous post,

android: culebra multi-device capabilities, minus the devices of course. You have to provide them.

Wouldn't it be great if Cloud Test Lab allows you to create your personalized tests, in addition to the automatically generated ones, using something like culebra GUI, where you can just point and click?
