Please add a feature that allows converting a fountain pen stroke into a pencil or other pen tools, as well as a line style conversion feature (solid, dashed, dotted).

Pen tool conversion
Fountain pen → Ballpoint pen

Fountain pen → Brush

Fountain pen → Pencil

Brush → Fountain pen

Brush → Ballpoint pen

Brush → Pencil

Pencil → Fountain pen

Pencil → Brush

Pencil → Ballpoint pen

Conversion to ballpoint pen (from brush, fountain pen, or pencil) is possible,
but reverse conversion from ballpoint pen to fountain pen, brush, or pencil is not feasible,
because ballpoint pen strokes cannot reproduce Apple Pencil tip tilt and pressure data.

Line style conversion
Solid line ↔ Dashed line

Solid line ↔ Dotted line
