Rendering multiple lineSymbols

[panne...@googlemail.com]

Hi all,
is there any way to draw more than one lineSymbol corresponding to one way? I already tried to modify the rendertheme-xml, by adding multiple lineSymbols to one way. However,  these symbols covered each other. I want to create a hiking map, where the symbol of each hiking-track, as you can see them on the information signs,  is shown on the map.  I am beginner in mapsforge and I didn't find any way to manage this issue.
Thanks a lot
