Add Fixes to system?

[kneighbour]

I would like to add Fixes to a flight plan. I would also like to add this function to the Find screen.  mainly fly IFR in X-Plane. but i am sure that this would be useful in VFR as well.

Are these fixes intersections? In which case they should already be searchable (you may need to enable them in the map tab if they are hidden)
