Merging / combining Fredo splines

Is is possible to combine multiple fredo-splines. I want to join them at their endpoints, then have the two original splines behave as a single spline that can be edited/adjusted going forward.

I didn't find the way. Meanwhile I kind of 'solve' it by converting them back to a primitive straight polylines and then convert them (together) to a single one of desired type.

Combining 2 splines into one would cause each spline to be (slightly) modified to ensure continuity at the junction.

This is not supported currently by FredoSpline, but can probably be done (although not trivial in the general case).

Same, by the way, for the split of splines, that is, cut a spline into pieces which are also splines.

Currently, the only thing you can do is to extend a spline by its extremity.
