Particle Console & Uploading New Firmware

Quick question about the Particle Console & using it to upload new firmware to the Photon or Electron.

If I have added a Electron with firmware 0.5.0 to my particle console and I want to upgrade that firmware Over The Air wirelessly to 0.5.2 or what ever the latest is how do I go about that?

As a test I would like to upgrade my current 0.5.0 Firmware Electron to the latest 0.5.2 firmware over the cellular network.

If my Electron is sleeping does this new dashboard use the feature @Bdub has mentioned in the past to wake it up if it sleeping while the cellular module is still powered on?

Any feedback is appreciated!
