Please, enable custom line style (dashed,line size, color) this features should be flexible

I see this thread is 3 years old. FigJam in 2024 still only has 2 connector line styles (solid and dashed) with no way to control the spacing of the dashes. Only 2 line sizes. No option for dot line or dash-dot-dash lines. One can add a custom color, but the color picker doesn’t “save” your color so you have to use the eyedropper or cut and paste every time.
It is difficult to create a complex or sophisticated diagram with FigJam without more styling on the lines. It can be done easily in Figma, so why not in FigJam?
