Is there any way to send custom values in the notification JSON from the ilime API? For my application, the notification needs to include a requestId that the app uses to download more data about the purpose for the notification. Here's what the JSON I've been sending looks like:

{
"aps" : { "alert" : "New data available" },
"requestId" : 23456
}

I didn't see any support for custom values in the documentation for the API or in the schema. Is there a way to do this? I might be able to work around this by using the requestId as a localization argument, but that seems like a hack.
