Is there a certificate for Articulate Storyline similar to MOS?

I am looking for a certificate that is similar in nature to the Microsoft Office Specialist (MOS). I have been searching the Internet and this site for information, but so far I have not been able to find any results that meet my criteria.

I am using the eBook, that was published last year, and the online tutorials like study guides, as I try to cram as much information into my head as possible. I know that most of it will not stick, but enough will. (It is a learning habit that I have used with other applications, like Microsoft Office.)

I want to be able to gauge my capabilities while using Articulate Storyline. Also, it would be nice to have something to backup a statement like, "I am an advanced (or expert) user of Articulate Storyline." I can do that with Microsoft Office because I have my MOS 2007 and 2010 Master certificates. They prove that I really know how to use those applications.

If something like an independent Certiport accredited certificate does not exist today, then are there plans to create one?

I want to avoid the situation of overstating my level of knowledge and then get blown out of the water by true experts of the application.
