Graphics

To make a long story short, I have an OGscript that has been working flawlessly in moving XPression around automatically after certain graphics have been used to load the next graphic needed. I need to modify this script to do the same thing with  MediaManager. In OGscript to utilize this in XPression, I make use of the command "rosstalk.sendMessage" utilizing the "SEQI" parameter. I find no commands like this for MediaManager. Any help I can get on this would be greatly appreciated. I know how I need to do everything. Just cannot find the command to send it in a GPI from Dashboard to MediaManager.
