Multiple Splines out of 1 Point?

Hay guys!
i’m new to this forum so sorry if my question is a duplicate and already solved. I didn’t find any solution at all.

I’m trying to create a Blueprint where i can create multiple Splinepoints connected to 1.
For example i have Splinepoint1 and create by click or something like that 4 new one which are attached to it.
also the ability to attach these 5 splines together. I’ve created with paint a example of my things just to make it more showable.

Also i have a problem with a splinemesh creation i’ve done i will also put a Image of it inside here. It shows the Texturestretching and the Messed up curves it creates and i don’t know why. The Terrain spline tool works fine, but on the carroad which is a bit lower then the sideways i’m flying on it cause of the collision.

Spline point can be connected to only two spline points - previous, and next one. You can connect it with 4 points in the same time and generate some seamless crossroad.
