Thanks for contacting Airship. My name is Chilun from Technical Support here at Airship and I would be happy to help with this.
The answer to you question is no. The Java library doesn't support those payload properties as it is. However, I'm currently working on finding a workaround so bear with me on this and I'll get back to you on that once I have it. Have asked internally about plans for adding those properties - will look to have an answer for you on this as soon as I have received it.
