Is it possible to customize the multi-SCO player?

Publishing using the Adobe Multi-SCO Packager works fine.  After import into my LMS (SumTotal Maestro) the course opens in a player with the SCOs listed on the left and navigation elements on the top.  I would like to customize this player interface in terms of layout, fonts, colors etc.  My LMS provider is telling me the "player" is generated by the authoring tool but I also heard it's generated in the LMS.  Is it possible to access this player and customize it? 

I'm using Captivate 7.  Output is to either SWF or HTML 5.

thanks.
