In App Purchase - how to pass developer payload when making purchase requests?

Solar2D Monetization (in-app purchases, ads, etc.)

I want to use a payload when making a purchase request, as suggested by the Android documentation for In-App Purchases.

see here: http://developer.android.com/google/play/billing/billing_best_practices.html#payload

Is this supported by the Corona sdk? I can’t find it in the documentation of the store library 

(http://docs.coronalabs.com/api/library/store/index.html)

Thanks
