Export to Powerpoint from Storyline

I agree with most on here that the ability to export or "save as" a PowerPoint is a requirement in our industry.  PowerPoint is not going away and it is the preferred medium for developing training in a training department setting.    I have many instructors that provide me with their raw PowerPoint presentations on a variety of different courses.  It is my job to take the PowerPoint info and create an eCourse, save as an LMS and upload to ur company LMS.  Simple right?  Why is PowerPoint needed you ask...

1 - Prior to publishing, the course is reviewed by our leadership for accuaracy, recommended changes etc.  To do this I need to save the SL project as an HTML5 file,  upload to our server and provide them with a shortcut to the link.  I also need to unlock all navigation restrictions to allow them to scrub each slide for content etc.  They do not have the ability to make changes to the presentation.  Furthermore, without the timeline counter they can't tell me exactly where the change needs to be made.  IE. "Change ....at 1.03 on slide 8."

2 - We are required to keep our source files in the event (all the time) that changes or revisions need to be made later on.  Happens all the time as companies grow.  Most of my instructors do not have StoryLine.  For them to make changes they must use the original source file which of course requires me to duplicate the SL back on to PowerPoint to allow them to make changes. Sorry but a static image on a word document doesn't work.

Don't get me wrong, I like using StoryLine because it's the best software out there to use for our LMS but it has some serious limitations.
