Is there a way on the iPhone app to set a custom notification sound (other than the short pre-built list)? In the App, when I go to Settings->Sounds, I can set the notification sound for each priority level, but I can only select from a small list of custom sounds or select System Default. I am trying to get a sound for critical alerts that will wake me up in the middle of the night, and none of the available options even come close. I don't want to change the default alert sound for my phone because of other notifications that would use that sound. I am running version 4.7.6 (build C611) of the Pulseway app. I am on iOS version 7.0.3.
