Hi,
Not that I am aware of.
Maybe you could get in touch with the author and mention you'd like support. Mention me as well, as I'll be willing to help him with a kick start for PlayMaker support ( giving coupons so that he can work with playmaker,making a few custom actions for him to get an idea of what to do, etc).
It's always a good idea to raise your voice to publishers for PlayMaker support. At this point, it's impossible now to keep up with supporting third party on our own anymore. I remember the days where I could provide support for all major assets on the asset store.... These days are long gone now... it's overwhelming...
Bye,
Jean
