Adding list to DialogFullScreenInfo.xml

I currently am able to add to labels using python and setproperty to the home screen. I cant figure out how to fill a list in an already open window gui.

HomeWindow = xbmcgui.Window( 10000 )
HomeWindow.setProperty( ‘trakt’ , rating_votes )

and call it using:

<info>Window(HOME).Property(trakt)</info>

How can I do the same with a list?

In short I have a list that is extracted of my currently playing in plex and want to show it ion the info screen while playing a movie but I want to use the current gui (I already have it working on another gui).

1. Fill the list extracted from plex. (DONE)
2. Append to a list (DONE)
3. setproperty so the list can be filled on the guis end.

Thank You
