Navigation - same track for 'To' and 'Return' way, choosing direction

Hi,

I've recently used navigation on trip that used the same way for both directions - to and return. Somewhere in the middle of first part I went off my route (intentionally, about 1km) and when I returned to my planned track, navigation directed me to my start/end point. Seems to be pretty logical, it tried to help to get to the end :). But still I wanted to go further. Is there any way to change direction of navigation in such case? Maybe I missed some features or settings? Any tips?

Regards,

Paweł
