Custom Notifications For Android Apps on Asus Flip (C100PA-DB02)

[Brew Swayne]

Is is possible to set custom notifications for Android apps on Chromebook? For example, I installed the Blue Email app on my Chromebook because I prefer it over the Gmail app on my phone and tablet and I don't care for the web version of Gmail at all. However, I haven't been able to figure out how to set a custom notification sound for new emails. When I go into the app settings, I'm given a list of notification sounds to choose from, but I still don't receive an audible notification when a new message arrives.

Is there something I'm not doing correctly or is this something that I'm just going to have to hope for in future ChromeOS updates?
