I got the section letters to be included in the XML at the right places (but not always, in the example below I have added a dummy section marker on the bar that follws after the bar I want the marker on, otherwise it will not be included in the file)

However it seems that the section markers are exported to XML but there are probably some bugs.(hard to see what is going on).
The XML seems to be loaded ok into MuseScore and GP8 with all the section markers correctly placed.
So it might be possible to manually mark up the blue/green changes, who knows.
