Just one quick question is there an option to add arrows to the planks ?

Depiction in the menu) that in one step shows all the helices as cylinders or "pipes" and all the strands as rectangular boxes or "planks". However, that tool has less flexibility in coloring - all the planks would be the same color as each other, for example.
