Sorry but only Adobe can answer that. I haven't seem anything suggesting it is on the way. I can only suggest you submit a feature request.
Please follow this link to report bugs and request features. The more people who do so, the higher it gets prioritised.

Post the link to that bug/feature in this thread and others can vote for it.
