Adding to Track Library

[Augydoggy]

Is there a way to add to the track library?  In the real world I'll be hand laying my track but in AnyRail I'm using On30 Micro Engineering track.  This has worked fine except where I'm using curved turnouts.  Since there are none for my scale in the track library I've been simply laying two pieces of track together to simulate what I need.  This has been fine for designing my layout but it was suggested to me to use a program to simulate running trains on the layout and I suspect that'll create a conflict with my phony turnouts.  For my layout I'm using Fast Tracks fixtures and there are PDFs available in full size to help "lay out" the layout.  Is there a way I could add these to the track library?
