display custom gpx file during activity?

Hello,

is it possible to show an imported gpx course during an activity? I have one field for the map anyway, that shows the track I'm doing at the moment, would be nice to have the imported one maybe in the same window in a different color, is that possible?

It works if I start my activity and from there start my gpx as navigation, but that gives me a lot of additional pages and annoying "off course" warnings. Just the map to check if im still following my prerecorded track would be enough.
