Add point actually already has a mode for doing that, some information on that here:

quote:
There are 2 different methods for adding curve points. If points for the curve are turned on and you click on the dashed hull between 2 existing points, a new point will be added with the same effect as if you had drawn the curve with that additional point. Other points will stay where they are currently located and the shape of the curve will change slightly.
The second mode for adding curve points is activated by clicking directly on a curve that does not have control points turned on - this will create a new point nearby the area you clicked, and existing points will shift slightly, but the shape of the curve will remain exactly the same as before.
So when you use Edit > Add pt, there are 2 modes to it, one mode is if you click on a control polygon hull line, that's the mode that adds in a new control point and keeps the control points in their current locations which will result in the curve shifting shape somewhat just like you have seen.
The second mode is if you click the point down directly on the curve rather than on the control polygon. You can do this with the control points being shown but if the control point hull is getting in your way you can turn off the points to make it easier to click directly on the curve. In this second mode the shape of the curve will not be modified at all, the curve will remain in its exact previous shape and instead the control points will shift somewhat and get refined with a new point inserted into the curve in the general area where you clicked.
Here is an example of that in action - again note if the control polygon is getting in your way of targeting the curve itself turn the points off and then use Add pt and click directly on the curve:
So note there that unlike the other add point way the shape of the curve remains completely fixed and does not change at all with this style of added points, which is what you were asking for if I understood correctly.
