Adding midpoints to (line) edges

[Dybkjær]

I am mainly illustrating origami diagrams, a relatively geometric discipline.

A common operation is to fold the paper, or a flap, into half. This translates into dividing an edge (a straight line between two nodes) by adding a new node between the end point nodes of the edge.

Could we get a feature in AD (iPad) supporting this? 

Could be: 

1. Select a segment (an edge). Press Add point (new operation, places the new point in the middle). This is how InkScape does it.
2. Oe better: Select n nodes. Press Distribute (new operation). This way might be more in line with the iPad AD way, and much more general.

Please note I am not asking how to construct the midpoint of an edge and place a node there. I know how to do this, several ways.

I am asking for an operation that directly supports something I do often, and which might be of general interest.

There is some partial support when the edges are vertical or horizontal (when holding one finger down while dragging the node with the pen),  but not for anything else.

My apologies if I have overlooked an existing operation on iPad AD.
