Horizontal Alignment - Tangent Point Symbols

Hi all,

I'm using Bentley Rail Track V8i and trying to display my horizontal alignments with two different tangent point symbols. (An unfilled dumbbell for Tangent/Spiral and Spiral/Tangent, then a filled mirrored triangle symbol for Spiral/Curve and Curve/Spiral). I can see that style selection per TP type is in 'View Horizontal Annotation/Styles' but how do you initially create the point styles to then select and display on alignments. All I have is the Default preference setting which displays nothing whatsoever.

Any advice would be greatly appreciated.

Thank-you
