Could the Pen Tool have a "sum curves" facility please?

Suppose that one has produced a representation of y=f(x) using the Pen Tool.

Suppose that one has also produced a representation of y=g(x) using the Pen Tool.

Could we have a facility such that one can select both curves and press a button somewhere and a single curve y=f(x) + g(x) is produced please?

Not done by summing the mathematical functions but by actually summing the curves as presented. That way it would work for any curves.

If the first curve has p points defined, whether sharp, smooth or smart; and the second curve has q points define, whether sharp, smooth or smart, then the result will have a maximum of (p+q) points defined: if a point is at the same value of x in both curves then only one point will be in the result, so there could be fewer than (p+q) points in the result.

How difficult would this be to program please?

I don't think I follow exactly what you are saying, but I think that advanced pen functionality is best fit in Affinity Designer rather than Publisher. Maybe your suggestion could go in the Designer forum.

I agree with @garrettm30 that this is a better fit for Designer, but I also don't think this is a potential feature of the pen tool, but rather a command to be buried in a menu somewhere or maybe an option to place on the toolbar, more like the boolean operations.
