instrument tracks, folder and organization

I like to use folder tracks to organize my bigger projects.

I like to export combinations of tracks using instrument and MIDI tracks so that i can recall the various combos according to the project requirements.

My problem is this. Nuendo will not save folder tracks.When I import a large amount of tracks i need to route them again in to folders to organize.

The “visibility” choice on the far left of my DAW will let me choose what i do and don’t want to see but it seems that you can’t group these tracks together unless you put them back in folders.

What i’d like to know is that if there is a way to import and export various track combos that will still be in groups in the visibility tab so that i don’t have to organize them once again in to folders when i recall.
