I'd love to be able to accept user input on a push notification.

I believe this is different than the 'Actionable' push notification requests.

I'd like to be able to send a notification that needs specific info from a user.

IE. I watch my credit card transactions. When I get a new one I want to send a notification to my phone to as the user provide a category. I'd love to use the Pushover APP to do this. 

I'd love a new type of message that opens the pushover app, prompts the user with a configured input form, and then POSTs that information to a configured URL.
