Controlling bend line, line type

How can I control the line type displayed for bend lines in draft?

Some are showing up dashed, some as center lines, some as solid lines.

Even within a single draft of a single part. if I flip the part over, it changes from dashed to solid. That part happens to be a contour flange.

In parts with tab & flange method, I get center lines.

In parts where multiple flanges are pulled at once, I also get get center lines.
