Currently, custom data can be passed using the OnSend event, but only applies for FileOperations and Upload, but missing from all other controller actions such as Download and GetImage.
It would be very handy to have a uniform way to send custom data to all controller actions. That would resolve so many issues others have reported with dynamic paths or other scenarios. There is a cumbersome way to deal with the DownLoad controller action but have not seen any workaround for GetImage.
Custom data should be an expected, but optional part of the controller actions. Since it exists for FileOperations and Upload, it must be simple enough to extend that to all controller actions.
