I've been pushing get a good distance of track laid on my route. My thinking was to lay it all in one type (Scalerail Wooden Ties, Main) then go back after and change the sidings and yard tracks to the appropriate track. To do so, I've been using the select tool, then highlighting the track I want to change, then selecting it from the flyout menu on the right side. When I do this, the majority of the track will change type, but not the actual junction/switch itself. (see picture below) Is there a proper method to do this, or do you HAVE to lay the junction with the proper track type the first time?

Any help would be appreciated
