Public new_map url parameter to select view mode

I want to be able to construct a URL that immediately shows all my (past or future) trips, not just the most recent year, e.g. public/myname/new_map?viewMode={all,past,planned,year}[;year1,year2,...] Possibly also &transportTypes=train,ferry,... Probably should override any cookies, and in fact set them to the values given in the URL. I can edit the URL myself, I don't really need a user interface for this, although others might want that.
