You're welcome! - A few months back I invested a few hours of time creating a list of all of the latest, available TRS19 3D/ 4D speed trees - and seasonal textures - PBR content etc., and then planted an example of each in rows or strips on a blank, single baseboard route.
My plantation now comes in extremely handy when I am looking for a particular tree or shrub-type when I am route-building. (Makes it much easier to select the "right look" than trying to scroll down the 'Add Object' list and looking at the thumbnail previews there, or trying to recall some of the obscure names given by some creators for otherwise excellent assets).
You can just go into route edit mode and mouse-over the trees that match the look you're looking for to see the name of the tree (or ground texture) so that you can put it into the new route.
(Change the month in the environment settings dialog to see seasonal differences).
Also remember that Preview Asset mode in Content Manager now allows you to preview the Seasonal appearance of all seasonal assets.
